“…In this paper, we follow a different approach to achieve a similar effect: we will introduce a controllable local propagation environment (CLPE) around the receiving terminals so that the overall propagation channel can be properly reconfigured to allow communication with the maximum possible number of users. The controllable propagation environment we propose is closely located to the transmitting terminals; in this paper, we realize it via employing parasitic elements, using some of the techniques that have been previously proposed for low-cost smart antennas [33][34][35][36]. In particular, these low-cost antennas were proposed for the optimization of the received power in point-to-point connections or for the reduction of the effect of interferences.…”

The capability of controlling and modifying wireless propagation channels is one of the prerogatives of beyond-5G systems. In this paper, we propose the use of a controllable local propagation environment surrounding the terminals, and analyze its positive effect on the multiplexing capability of massive MIMO systems. In particular, we focus on using a few switched passive elements surrounding each terminal. In this way, the modification of the propagation environment is not realized by means of a single structure, as in reconfigurable intelligent surfaces (RIS), but is achieved by the cooperative work of all the terminals. By employing numerical simulations, we show that the proposed system outperforms its non-reconfigurable counterpart in terms of the number of contemporary connected users. Moreover, the optimized system enables a substantial increase in the minimum received power by the terminals, thus guaranteeing superior channel fairness.

“…As one of the most important characteristics of electromagnetic (EM) waves, polarization conversion has wide applications in engineering areas [1], such as antennas [2], navigations [3], optics [4] and communication [5]. Over the last few years, multifarious polarization conversions were proposed, including using birefringence material [6], and crystals [7].…”

A tunable dual-frequency metamaterial graphene polarization converter in the infrared range is put forward in this paper. The proposed converter is made up of 3 layers—the bottom gold layer, the middle silicon dioxide layer and the upper graphene layer. The simulated results show that the polarization converter can simultaneously work at two resonant frequencies of 36.82 and 41.38 THz. The polarization conversion rates are up to 0.9992 at 36.82 THz and 0.9969 at 41.38 THz under the certain normal condition when Fermi energy is given to 1.0 eV, showing the high efficiency of the polarization converter. Moreover, the converter shows its stable working performance under the change of the incident angle and the geometrical size. Meanwhile, without varying the nanostructure, the resonant frequencies can be flexibly adjusted by controlling the Fermi energy. The superior performance of the proposed graphene polarization converter indicates a broad prospect that a large number of applications such as infrared imaging sensors, modulators, switches, photonic and biochemical sensors, light harvesting, thermal detection and electromagnetic energy converter will apply it.
