Non-radiating and radiating configurations driven by left-handed metamaterials

Abstract

It is shown that a pair of identical emitters (e.g. wire dipole antennas) in the focal points of a disc, made of left-handed metamaterial (a “perfect” lens), form a non-radiating electromagnetic configuration. The emitters are fed with voltages of equal magnitude and πout-of-phase. Detailed finite-difference time-domain (FDTD) modeling shows that there are… (More)
