Abstract

Near-field metasurface based beam steering are finding many applications. However, the traditional cells designed for such metasurfaces cannot produce all the required phase shifts with high amplitudes, ultimately contributing to high steering error. This paper presents a cell geometry, Flanched-Cross, that provides more accurate phase shifts with higher amplitudes than the traditional square patch cells. Simulation results verify that the Flanched-Cross cell produces a higher number of phase shifts with the error between 0.04°-1.2° only as compared to a square patch cell with an error between 0.1°-2.2° for the design of a beam-steering metasurface.
