Empirical Validation of the Impedance-Based RIS Channel Model in an Indoor Scattering Environment
Placido Mursia, Taghrid Mazloum, Frederic Munoz +7
Ensuring the precision of channel modeling plays a pivotal role in the development of wireless communication systems, and this requirement remains a persistent challenge within the…
Engineering of intelligent reflecting surfaces: Reflection locality and angular stability
Javad Shabanpour, Vladimir Lenets, Geoffroy Lerosey +2
Reconfigurable intelligent surfaces (RISs) are electromagnetically passive controllable structures, deflecting the incident wave beam in directions predefined by the control signal…
Model-free Optimization and Experimental Validation of RIS-assisted Wireless Communications under Rich Multipath Fading
Tianrui Chen, Minglei You, Yangyishi Zhang +6
Reconfigurable intelligent surface (RIS) devices have emerged as an effective way to control the propagation channels for enhancing the end-users' performance. However, RIS optimiz…
