“…On these lines, [30] proposes a 5 GHz RIS design with 2-bit phase resolution by leveraging on transmission lines to generate different phase shifts at each RIS element whereas the RF-switches are used to route the signals on the optimal line (according to the RIS configuration). Besides, the work in [7] builds upon the transmission-line method to design a 3-bit resolution RIS and introduces the possibility of setting each of the RIS elements (separately) to fully dissipate the impinging RF power, i.e., effectively turning off some of the RIS elements, and virtually changing the overall shape of the array.…”

“…None of the above-mentioned works deal with selfconfiguring RIS-empowered networks without relying on a control channel. Moreover, although [7] hints to an absorption mode for RIS elements, such energy is only dissipated over a matched load and is not used to power the device and enable its energy self-sufficiency, thereby underlining the contributions and novelty of the present paper.…”

“…As operational RISs draw limited amount of energy [7], they may run on compact batteries, thereby requiring no continuous external power supply but calling for periodic maintenance, which might limit their operational availability.

Reconfigurable Intelligent Surfaces (RISs) are considered one of the key disruptive technologies towards future 6G networks. RISs revolutionize the traditional wireless communication paradigm by controlling the wave propagation properties of the impinging signals at will. A major roadblock for RIS is though the need for a fast and complex control channel to continuously adapt to the ever-changing wireless channel conditions. In this paper, we ask ourselves the question: Would it be feasible to remove the need for control channels for RISs? We analyze the feasibility of devising Self-Configuring Smart Surfaces that can be easily and seamlessly installed throughout the environment, following the new Internet-of-Surfaces (IoS) paradigm, without requiring modifications of the deployed mobile network. To this aim we design MARISA, a self-configuring metasurfaces absorption and reflection solution. Our results show that MARISA achieves outstanding performance, rivaling with state-of-the-art control channel-driven RISs solutions.

Recently reconfigurable intelligent surface (RIS) has attracted great attention because it can create a smart wireless environment. Hence it can enhance the capacity and coverage of the wireless network significantly. A thorough review of RISs has been presented in this paper focusing on the hardware aspect of the RIS. Beyond-5G/6G communication will have a smart propagation environment, where RIS can be used for such communications. RIS consists of various small unit cells. The unit cells should have some tunning mechanism so that the incoming waves can be reflected or transmitted in the desired direction. It is possible to tune the impedance of the unit cells using PIN diodes, varactor didoes, microelectromechanical (MEMS), thermal, and other ways. In this paper, initially, the background of RIS has been discussed where RIS is going to play a significant role in beyond-5G/6G communications. We have also added the theoretical background of RIS and motivations to writing this paper. After that several published papers in the literature have been presented so that the readers can get an overall idea about the RIS and its hardware. Hence, this paper will be very useful for practitioner engineers and researchers. RISs have been presented in various tables and various parameters have been presented. We have discussed challenges and solutions for the hardware of the RIS design. We have also discussed potential research and research gap that can be explored in the future. Lastly, we have added a conclusion for this review paper.INDEX TERMS Reconfigurable intelligent surface (RIS), beyond-5G/6G communication, reflectarray, PIN diode, varactor diode.

Reconfigurable Intelligent Surfaces (RISs) are a promising way to improve the performance of wireless networks. However, despite the high interest in the research community, no flexible enough simulation platform allows for studying the performance of wireless communication systems with RIS in complex scenarios. To address this issue, the paper presents an open-source channel simulation platform to study RIS in wireless communication systems. The developed open-source platform extends the QuaDRiGa channel model, which is widely used for the performance evaluation of 5G and Wi-Fi networks with multiple antennas. The paper shows how to use the platform -called QRIS -to evaluate RIS in various frequency conditions, such as indoor/outdoor scenarios and multiple-RIS deployments. INDEX TERMS Reconfigurable intelligent surface (RIS), channel modeling, MIMO systems, simulation, 5G and beyond, future Wi-Fi.
