A beam-steerable antenna based on the spatial filtering property of hyperbolically anisotropic metamaterials

Abstract

The purpose of this work is to investigate the use of the spatial filtering property of hyperbolically anisotropic metamaterials to achieve beam-steering.The present work employs the aforementioned concept in a fixed-frequency antenna array. The radiation beam angle is made tunable by varying the permeability tensor of the metamaterial on which the antenna is realized.
