Abstract

Using a coordinate transformation on a folded geometry, appropriate transformation media can make an embedded antenna appear as if it is positioned at a virtual location. For the TE polarization in two dimensions, embedding media for an electric line source are designed in transmission-line and inclusion-based resonant metamaterial configurations. For a line source positioned inside a recess in a conducting ground plane, the metamaterials are specifically designed to form a virtual line source above the ground plane. Metamaterial design details and simulation results for predicted radiation patterns are presented.
