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

On Half-Power Beamwidth of Intelligent Reflecting Surface [PDF]
IEEE Communications Letters, 2021 Half-power beamwidth (HPBW) is a key parameter to measure the performance of antenna array and the newly proposed intelligent reflecting surface (IRS) systems. In this paper, we first establish a system model for IRS in uniform linear array (ULA) and uniform rectangular array (URA) configurations, then the IRS HPBW in both cases are derived under the ...
