Properties of Near Field Focusing for Three-Dimensional Large Intelligent Surface
Jiawang Li, Mats Gustafsson, Alireza Saberkari +1
This work investigates near-field focusing using a three-dimensional (3D) large intelligent surface (LIS) across frequencies and polarizations. Specifically, the LIS elements are d…
