While 5G is being tested worldwide and anticipated to be rolled out gradually in 2019, researchers around the world are beginning to turn their attention to what 6G might be in 10+ years time, and there are already initiatives in various countries focusing on the research of possible 6G technologies. This article aims to extend the vision of 5G to...

... growth in the global mobile data traffic, expecting to experience a 23 times increase in 2021 in data volume compared to the entire global Internet traffic in 2005. The forecast by ITU predicts that the trend of exponential growth will continue, and by 2030, the overall mobile data traffic will reach 5 zettabytes (ZB) per month, as shown in Fig. 1. The fifth generation (5G) is the latest attempt that brings mobile communications technology up to speed to meet the requirements for the next 10 years. It is expected that near 2030 5G will reach its limits and the chase ...

... materials (SDM) can actually be deployed in a much larger scale to provide a radio-controllable environ- ment [11]. By doing so, it is possible to control the interference by altering the propagation properties of the environment. For example, SDM can be laid on walls to provide insulation for unintended radio signals as illustrated in Fig. 3 [11]. Smart reflective surfaces in [3] follow the same spirit despite focusing on relaying signals and using standard materials. Programmable metasurfaces indeed can do much more than simply altering propagation environments. They could replace the design architecture of wireless transceivers entirely. Recent results reveal that a ...

By doing so, it is possible to control the propagation environment by altering its electromagnetic properties. For example, SDM can be laid on walls to provide insulation for unintended radio signals as shown in Fig. 3 [11]. LISs on buildings or in indoor environments are predicted by many to make their mark in 6G. Programmable metasurfaces indeed can do much more than simply altering propagation environments. They could replace the design architecture of wireless transceivers entirely. Recent results reveal that a metasurface can be programmed to vary ...

In this work, we show that detecting the polarization information of χcJ→ϕϕ(J=0,1,2) could be a practical way to test the hadronic loop effect in these decays. Our results show that the predicted ratios of helicity amplitudes are less dependent on the parameters involved in the calculation. The ratios are determined to be |F1,1(0)/F0,0(0)|≈0.359, |...
