Sparse Arrays Enable Near-Field Constant-Distance Focusing with Reduced Focal Shift
Jiawang Li, Yingjie Xu, Hanieh Aliakbari
In near-field beam focusing for finite-sized arrays, focal shift is a non-negligible issue. The actual focal point often appears closer to the array than the predefined focal dista…

Near-Field Collinear Dipole Array Design with Dual-Polarization Operation for Wireless Power Transfer
Jiawang Li
A large intelligent surface (LIS) is a promising approach to enhancing 6G performance in sub-10 GHz frequency bands. An analysis of the horizontal dipole linear array reveals that…
