Abstract :
A transmission-line metamaterial design of a material-embedded line source radiating inside a ground recess is presented. The media embedding the recessed line source is designed such that the embedded current creates the same radiation pattern as a line source over a flat conducting ground plane. A numerical example based on circuit simulations is shown to validate the effectiveness of the embedded design at the design frequency.
