Highly directive antenna based on one-dimensional anisotropic metamaterials

Abstract

In this paper, we achieve highly directive emission based on left-handed metamaterial. By employing the anisotropic characteristics, the electromagnetic (EM) wave propagates along only one direction inside the medium and has a quasi-plane phase front; the electromagnetic (EM) waves emitted from the medium would behave high directional. This property is verified by both the numerical simulation and the experimental measurement.
