Introduction
In the whole world electricity transfer from power station to
everywhere is through wire. Wireless power transfer technology can
potentially reduce or eliminate the need for wires and batteries. Wireless
transmission is useful to power electrical devices where interconnecting
wires are inconvenient, hazardous, or are not possible. Wireless power
transfer technology reduces the use of electric wire which is made of
copper and aluminum metal. e metal which are used to make electric
wire will extinct in future. If we implement wireless power transfer
technology the use of electric wire will reduce. It would be benecial if in
future, we can implement wireless power transfer technology to transfer
power from power station to everywhere without the need of wire. In
section 2 dierent categories of wireless power technique are discussed,
whereas in section 3 represents the various experimental proof of
wireless power transfer, section 4 discusses dierent applications of
wireless power transfer and nally section 5 discusses the potential
future application of wireless power transfer technology.
Wireless Power Technique Categories
Non- radiative
In near eld or non-radiative techniques, by magnetic elds using
inductive coupling between coils of wire power is transferred over
short distances, or by electric elds using capacitive coupling between
metal electrodes. In wireless technology, inductive coupling is widely
used; phones and electric toothbrushes, RFID tags, and chargers for
implantable medical devices like articial cardiac pacemakers, or
electric vehicles are included its application [1].
Near-eld transfer: In near-eld transfer coupling of two coils
are needed to transfer power. rough magnetic eld coupling a
transformer is transferring energy wirelessly, although it was invented
more than 100 years ago. e transfer eciency drops drastically if we
remove the iron core and move the two coils apart [2]. at is why the
two coils must be put close enough to each other. is kind of method is
already launched in the market. For example, most electric toothbrushes
are using wireless chargers, which are much safer than cable chargers in
wet environment [3].
e frequency of the transmitter and receiver coils is determined
by the material and shape of the coil, transfer eciency will decrease
much more slowly when they are moved apart. Prof. Marin Soljacic
led a group from MIT, has succeeded in transferring electric energy
(60 Watt) between two coils more than two meters apart through non-
radiative electromagnetic eld, as shown in Figure 1 [4]. ere is almost
no interference with TV, radio or Wi-Fi signals and it happens in near
eld usually working at 50 or 60Hz. e major problem the possibility
of inuence on human health. But one thing is that almost all materials
that form human body are non-magnetic, so they cannot interact with
magnetic eld, even to several Tesla like that in a modern MRI machine
[4,5]. Such kind of magnetic-eld-is there that is quite safe to people
within the transfer range [3].

Radiative
In far-eld or radiative techniques, power is transferred by beams,
like microwaves or laser beams also called power beaming. Power
beaming techniques can transport energy longer distances. Solar
power satellites, and wireless powered drone aircra are proposed
applications [6-8].
Far-eld transfer: To transfer energy wirelessly over long ranges,
far-eld transfer is used.
• Microwaves: In far-eld radiative electromagnetic wave is used.
Dierent method uses electromagnetic waves within dierent
wave band. In the early times, there were many experiments with
radio and microwaves [9]. To achieve sucient directionality,
the wavelength of the antennas must be longer. An antenna
with a dimension of several meters to several kilometers which
requires the speed of light in the air is about 3 x 108 m/s and
the wavelength of radio and microwaves is about 1 meter. To
transfer energy to smaller objects shorter wavelength is used.
e electromagnetic wave used the waveband of radio, TV,
cell phone and Wi-Fi, with a signal intensity several orders of
magnitude larger [10].
• Lasers: In the case of electromagnetic eld show in Figure 2
power can be transmitted by converting electricity into a laser
beam. at is then pointed at a photovoltaic cell [11,12]. In
the case the power is beamed at a receiver that can convert it
to electrical energy, so this mechanism is generally known as
‘power beaming’ technology. Special photovoltaic laser power
converters are optimized for monochromatic light conversion
that are applied at the receiver [13]. is technology used in
military weapons [14-16] and aerospace [17,18] applications.
Various Experimental Proof of Wireless Power Transfer
• Resonant inductive coupling, also known as “electro-dynamic
induction” used by Nikola Tesla in 1894 to wirelessly light up
phosphorescent and incandescent lamps. at was situated at
the 35 South Fih Avenue laboratory, and later at the 46 E.
Houston Street laboratory in New York City [19-21]. A device
[22] called the high-voltage was patented by Nikola Tesla in
1897.
• In 1910 an experiment was held using incandescent light
powered wirelessly by electromagnetic induction. e bottom
of a large cylinder was made by using an electromagnet, a coil
of wire with alternating current through it. It creates a magnetic
eld. Above the magnet’s pole the lamp is attached to another
coil of wire. e magnetic eld generate electricity that lights
the lamp. e lamp then looks like an original Edison lamp
with a carbon lament [23].
• Rectenna was invented by Brown in 1964 which could
eciently convert microwaves to DC power, and the rst
wireless-powered aircra demonstrated in 1964, a model
helicopter powered by microwaves beamed from the ground
[24,25].
• In California 1975 Wireless high-power transmission using
microwaves experiments in the tens of kilowatts have been
performed at Goldstone [26-28].
• e rst MPT experiment in space was carried out by Hiroshi
Matsumoto’s team in 1983. e experiment was called MINIX
(Microwave Ionosphere Nonlinear Interaction Experiment)
[29,30].
• In 1987 fuel-free airplane ight experiment was succeeded
by Canadian group with MPT which was called SHARP
(Stationary High-Altitude Relay Platform) with 2.45 GHz [31].
• Several eld MPT experiments have been conducted over the
years In Japan. A fuel-free ight experiment was conducted
successfully by joint collaborative group using phased-array
technology, which was referred to as the Microwave Lied
Airplane Experiment (MILAX) in 1992 [32].
• From the University of Auckland in New Zealand, Professor
John Boys and Professor Grant Covic developed systems to
transfer large amounts of energy across small air gaps in 1993
[33,34]. In Japan this system was practical used as the moving
crane and the AGV non-contact power supply [35].
• In 1994-95 power company and universities made Ground-to-
Ground MPT experiment [36].
• In 1997 at Grand Bassin on Reunion Island, Microwave Power
Transmission experiment was conducted [37].
• A lightweight unmanned model plane powered by a laser beam
was demonstrated NASA’s Dryden Flight Research Center in
2003. Photocells from a beam of infrared light from a ground-
based laser generated the small model plane’s motor was
powered by electricity, while a control system kept the laser
pointed at the plane [38].
• Marin Soljačić along with other researchers at the Massachusetts
Institute of Technology applied in electromagnetic theory,
the wireless power transmission concept based on strongly-
coupled resonators in November 2006 [39-41].
• A long-range Microwave Power Transmission demonstration
was realized on one of the islands of Hawaii in May 2008.
Managed Energy Technologies of the U.S organized the
demonstration and involved the wireless transmission of
energy [42].
• Researchers at the university of Korea Advanced Institute of
Science and Technology (KAIST) have developed an electric
transport system that is called Online Electric Vehicle, OLEV.
e vehicles get power wirelessly from cables via non-contact
magnetic charging that are kept under the surface of the road.
To manage trac congestion and to improve eciency by
reducing energy consumption, this technique is established. In
Figure 2: Electric energy is transferred to a strong beam of radio or
microwave by a dish-like antenna, travels through the atmosphere and then
received by another antenna which transfers it back to output power supply.

Applications of Wireless Power Transmission
Transmission of power to the portable devices wirelessly
In the below Figure 3 show the overall system is made using charger
pad and the battery. To transfer energy from the charging pad to the
battery each part has planar coils. e charging pad and battery can
communicate with each other cause the electrical energy is modulated.
Before transmits full power to the battery, the charging pad verify
that a valid battery is in place or not. is communication continues
throughout the entire charging process to conrm the battery is still
in place [50].
Wirelessly charging of electric vehicle
According to Figure 4 a charging pad sits on the ground, connected
to a wall-mounted power adapter. All the car parks over it. On the
backside of the car there is a receiver when charger detects the receiver
within range, it automatically starts charging [51].
Wirelessly charging of public transport
Every electric bus has a wireless charging receiver. According
to Figure 5 Wireless chargers are embedded inthe hard surface of
a road or under the road surface at regular intervals. When the bus
is stopped no need to plug in or no need to connect with wireless
chargers. It will automatically have charged. It’s a motion bus. These
kinds of buses are already tested in the UK, Italy, the Netherlands,
and South Korea [50].

Future scope of wireless power transfer technology
In future we can use electric appliances by using electricity without
wire. In the below, discussing some potential scope of using wireless
power transfer technology.
Solar Power Satellite
Satellite with solar panel is used to capture maximum amount of
solar energy from the sun in the space. Satellite consists of microwave
transmitter which is used to convert power into microwave for
transmission. According to Figure 7 transmitting microwave from the
satellite present in space received by the microwave receiving antenna
situated into the earth. is microwave receives antenna then convert
microwave into electricity. en this electricity can be used to power
home and oce etc.
Wirelessly powered home appliances
In future there will be a transmitting device inside home that
will transmit power to all the home appliances such as Television,
Laptop, Lamp, Iron, Sound Box, Fridge, Mobile etc. show in Figure 8.
Transmitting device transmit power and all the appliances will receive
that power through receiving devices set up inside into all appliances.
Wirelessly charging of electric vehicle on way
According to Figure 9 in future there will be no need to stop and
charge the electrical vehicles. On the way charging can be done. In this
concept power beam transmitter will be connected to highways, busy
trac areas with power source. which converts electricity into power
beam and then that beam will transmitted to the electrical vehicle
which consist power beam receiver that convert power beam into
electrical power for the charging of battery inside the vehicle.
Universal power source in emergency
In an emergency or disaster situation where all the communication
medium and power system has broken down. Communication
immediately aer a disaster situation is an important component
of response and recovery; it connects aected people, families and
communities with support system and other family members. In this
situation an emergency power source may help to provide nessesary
power source to power their communication devices so that they can
easily connect with their family and rescue services as show in Figure
10. An universal power source consists of an airship built in power
trasmittor which act as power source and drons; which consists of power
receiving and trasmitting device which provide basic communication
as well basic wireless power to the aected people.

Wirelessly powered train
According to Figure 11 in future train may get power wirelessly.
ere will be no need to connects the train with wire. In this system
a dual mode power receiver and transmitter will connect to the
pole. Each station will have a pole with the dual mode transmitter
and receiver. Power come from the power station that dual mode
transmitter captures the power and transmit the power. By using dual
mode transmitter power receive and transmit happen simultaneously.
ese powers will be received by the receiver that xed in the roof of
the train. In this process there is no need to use wire.
Wirelessly power supply to house from power station
In future clean and green power generation may be done using the
renewable source of energy. Figure 12 denes power may be supplied
to our houses wirelessly. Power transmitting antenna connected with
the power supply providing station then power transmitting antenna
convert electric power into microwave then transmit it to the nearest
dual mode power receiving and transmitting antenna which transmit
this microwave to nearest antenna which is connected nearest to the
house. e house has its power receiving antenna which converts this
microwave into electrical power. is electric power than utilize by the
house.
Wirelessly controlling drone to extinguish the re
In future drone may be used to extinguish the re. Drone may carry
the water pipe and set the pipe to exact location that will be controlling
by the people using remote control system. Figure 13 denes drone
may get the power from transmitter establish in the re down car.
Transmitter transmits power and drone will have a receiver device that
will receive the power and work properly until the power has stopped.
Drone is very useful because where people cannot reach drone can
reach there and can capture pictures, videos of that area situation. In
emergency, it is not possible to connect the drone with wire, so this
process will be very useful.

can take measurable step quickly.
Wirelessly powered smart city
According to Figure 15 a city can be a smart city using wireless
technology. We can use power from power station without wire
through transmitter and receiver. Transmitter transmit electricity from
power station and a receiver receive the power and supply the power
between houses, cars, trains, oces even emergency areas where wired
technology is impossible to set up. By using wireless technology our
environment will be carbon dioxide gas free. We get beneted because
our environment will be clean and harmful gas free that emits from car,
train or other vehicles.
Conclusion
Now a day, we are using technology wirelessly like our phone,
which is a very big example of it but if we implement this method to use
modern technology by using wireless method then our communication
will be strong and smooth. In this paper, we have discussed about
wireless power transmission technology and its various applications
