Abstract and Figures

This paper presents an experimental setup for the wideband RF characterization of plasma Micro Hollow Cathode Sustained Discharge (MHCD). This microdischarge is studied as a candidate for integrated active component in antennas, using the change of permittivity caused by the presence of plasma. The measurement setup consists of a 50 Ω microstrip line with a single MHCD placed in its center. The measurement of the scattering parameters of the experimental device permits the evaluation of the complex permittivity and conductivity of the MHCD.

... However, few studies have considered the characterization of the interaction between a RF electromagnetic wave and a very localized microplasma discharge. Recently, a measurement setup has been proposed and used to evaluate the RF/microplasma interaction [10]. It consists of a 50 Ω microstrip line with a Micro-Hollow Cathode Sustained Discharge (MCSD) in its center [11], [12]. ...
... Its objective is to measure the influence of the MCSD over the S parameters of the inverted microstrip line from 0.1 to 10 GHz. The main difference with the previous measurement setup is the absence of dielectric contrast between the region where the RF electromagnetic wave propagates and the region that hosts the plasma [10]. Figure 2 presents a cut view of the new device. ...
Conference Paper
This paper presents an experimental study of the RF/microplasma interaction by the use of an inverted microstrip line. Microplasma discharges present physical characteristics that may be interesting for reconfigurable RF components. A measurement setup that consists of a 50 Ω inverted microstrip line with a single microplasma discharge placed in its center is proposed to measure the RF/microplasma interaction. The characterization is based on the influence of the plasma discharge over the S parameters of the line. Several measurements are presented. The main effects of the plasma discharge on the transmission line are a slight increase of the reflected power as well as an absorption of the incident power.
... In particular, plasma parameters can be controlled by external variables, such as the power injected to the discharge that has a direct influence on the electron density, and the gas pressure, and this has an influence over the plasma collision frequency [26]. This characteristic makes the cold plasma discharge suitable for the implementation of reconfigurable high-frequency devices, due to the active control and variation of the plasma permittivity, and therefore the variation of how the EM wave interacts with the discharge and the device [27][28][29][30][31][32]. ...

This article presents a parametric study using full-wave simulations about the potential use of cold plasma discharges to achieve frequency reconfiguration on a Sievenpiper mushroom metasurface. The study was done by inserting plasma tubes in between the patches of the mushroom structure, in three different positions with respect to the top of the metasurface, and varying the electronic density while keeping the plasma collision frequency. The obtained results show that it is possible to shift the stop-band generated by the metasurface around 25% towards lower frequencies for an electron density value inside the tubes of 1014 cm−3, when they are placed in between the top patches of the metasurface. Additional insertion losses are exhibited when operating near the plasma frequency.
... Sin embargo, gran parte de esos elementos solo pueden ser utilizados en rangos bajos o medianos de potencia microondas. Es en este contexto donde el uso de las descargas de plasma como elemento para la reconfiguración que pueda manejar altas potencias de microondas ha sido estudiado [2][3]. ...

This paper proposes the study of an inverted microstrip plasma-based reconfigurable antenna. The scope is to generate controlled microplasma inside the cavity between the antenna ground plane and its main conductor. This plasma will modify the resonant frequency of the antenna. The interest of using a plasma discharge as an active reconfigurable element is its switching time and mainly its capability of handling high microwave power. It was demonstrated, theoretically, that the reconfiguration frequency of a microstrip patch antenna with a microdischarge in its cavity, depends on the electron density of the plasma. Furthermore, a prototype of an X-Band inverted microstrip patch antenna, which integrates a microdischarge, was implemented. The measured frequency excursion for this prototype was 180 MHz.

A cold plasma-based re-configurable rectangular microstrip antenna has been computationally investigated. A power efficient frequency tunable patch antenna design is proposed wherein the substrate is replaced by a combination of air and plasma slots. The novel design consisting of plasma elements in localised regions achieves good tunability with minimal power requirements. Significant amount of frequency reconfigurability is achieved by varying the plasma density and slot configuration. A parametric study comparing the approximate power requirements and tunability of different designs has been presented. Finally the radiation properties of the proposed microplasma-based microstrip antenna has been evaluated.

The realization of a dual dihedral corner-reflector antenna (CRA) on a single ground plane by using low cost plasma lamps as reflective elements is presented in this paper. The commercially available compact fluorescent lamps (CFL) are arranged in dihedral coordination to transform classical omnidirectional beam shape into several forward beams. The novel prototype is realized and its performances are compared with simulations. The energized CFLs work as conductors with low conductivity offer good gain values with the maximum is more than 10.5dBi at 2.4 GHz. The beams are changeable electronically within seconds from one to another.

This paper presents a novel concept to tune the resonant frequency of an evanescent-mode substrate integrated waveguide resonator while maintaining a high-Q in the tuned frequency range. The tunability is based on the insertion of vertical switchable capacitive post within SIW cavity. The filter is tuned from 18 GHz to 7.5 GHz, with insertion losses ranging from 0.8 to 2 dB in the frequency range for 1.4% bandwidth filter. The main interest of this work is the use of the argon material under high pressure and DC voltage to generate a dense plasma media.

We report in this paper experimental measurements in order to validate the concept of switchable electromagnetic band gap filters based on plasma capillaries in the microwave regime. The plasma tube is embedded inside the structure to create a bistable (plasma on or off) punctual defect. We first investigate two kinds of discharge tubes: Ar–Hg and pure Ne, which we then use to experimentally achieve plasma-based reconfigurable applications, namely, a two-port coupler and a two-port demultiplexer.

Direct current glow discharges have been operated in atmospheric air by using 100 μm microhollow cathode discharges as plasma cathodes. The glow discharges were operated at currents of up to 22 mA, corresponding to current densities of 3.8 A/cm2 and at average electric fields of 1.2 kV/cm. Electron densities in the glow are in the range from 1012 to 1013 cm−3. Varying the current of the microhollow cathode discharge allows us to control the current in the atmospheric pressure glow discharge. Large volume atmospheric pressure air plasmas can be generated by operating microhollow cathode discharges in parallel.

Microdischarges sustained at high gas pressure in specific geometries can be very stable. A particular type of microdischarge, which is the microhollow cathode discharge (MHCD), can be used as an electron source to sustain a larger volume discharge. In this paper, we present results from a numerical study of a microcathode sustained discharge (MCSD) as part of a three-electrode system consisting of an MHCD and an MCSD. The time evolution of the plasma in the MCSD region is shown. Our discussion is focused on the ignition of the MCSD assisted by the electrons coming from the MHCD.

This experimental and theoretical study examines the excitation of a plasma antenna using an Argon surface wave discharge operating at 500 MHz with RF power levels up to 120 W and pressures between 0.03 and 0.5 mb. The results show that the length of the plasma column increases as the square root of the applied power, that the plasma density decreases linearly from the wave launcher to the end of the column and that these results are consistent with a simple global model of the antenna. Since noise is critical to communication systems, the noise generated by the plasma was measured from 10 MHz to 250 MHz. Between 50 MHz and 250 MHz the excess noise temperature was found to be 17.2±1.0 dB above 290 K. This corresponds to a thermal noise source at 1.4±0.3 eV compared with an electron temperature of 1.65 eV predicted by the model. © 2003 American Institute of Physics

Plasma antennas are just as effective as metal antennas. They can transmit, receive, and reflect radio waves just as well as metal antennas. In addition, plasma generated noise does not appear to be a problem.

This corresponds to an ohmic thermal noise source at 1.4±0.3 eV, compared with an electron temperature of 1.65 eV predicted by the global model. Estimates of the electrical conductivity of the plasma column based on measured electron number densities lead to an antenna efficiency of about 65% at a transmission frequency of 100 MHz and an increase in total antenna noise of 1 dB due to the plasma. Theoretical modeling and experimental observations of the radiation pattern of the antenna show that the linear variation of conductivity and finite resistance of the column lead to a reduction in the depth of the s in the radiation pattern and a consequent increase in the width of the main lobe.
