Some antenna applications of negative-refractive-index transmission-line (NRI-TL) metamaterials (original) (raw)

2006 IEEE Antennas and Propagation Society International Symposium, 2006

Abstract

Metamaterials are artificial structures engineered to exhibit unusual electromagnetic properties. Metamaterials (MTM) that exhibit a simultaneously negative electric permittivity epsi and magnetic permeability mu, and thus a negative refractive index (NRI), have recently attracted considerable attention in the electromagnetic community. This has been motivated by the potential to create new microwave and antenna devices that exhibit superior characteristics compared to
