Intelligent reflecting surface‐aided network planning
IET Communications, 2022 Abstract Intelligent reflecting surface (IRS) composed of a large number of low‐cost, phase‐adjustable passive reflecting elements, which is an attractive solution of overcoming the signal attenuation and interference. IRS can be used as a low‐power passive system with signal enhancement and interference suppression.

SWIPT With Intelligent Reflecting Surfaces Under Spatial Correlation [PDF]
IEEE Wireless Communications Letters, 2021 Intelligent reflecting surfaces (IRSs) can be beneficial to both information and energy transfer, due to the gains achieved by their multiple elements. In this work, we deal with the impact of spatial correlation between the IRS elements, in the context of simultaneous wireless information and power transfer.

Degrees of Freedom of the Wireless X-Network Assisted by Intelligent Reflecting Surfaces
IEEE Open Journal of the Communications Society, 2023 In this paper, we study the DoF of the time-selective $M\times N$ wireless $X$ -network assisted by an IRS. It is well-known that the DoF of the $M\times N$ wireless $X$ -network is ${}\frac {MN}{M+N-1}$ .
