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.
