On the Optimal Number of Reflecting Elements for Reconfigurable Intelligent Surfaces [PDF]

open access: yesIEEE Wireless Communications Letters, 2021
This work considers a point-to-point link where a reconfigurable intelligent surface assists the communication between transmitter and receiver. The system rate, energy efficiency, and their trade-off are optimized with respect to the number of individually tunable elements of the intelligent surface.

Feasibility of a Plasma-Based Intelligent Reflective Surface

open access: yesIEEE Access, 2022
Gaseous Plasma Antennas are devices in which an ionized gas (i.e., plasma) is exploited to transmit and receive Electromagnetic waves. Their main advantage over metallic systems is the possibility to reconfigure the antenna performance (e.g., radiation pattern) by electronically varying the plasma parameters (e.g., density).
