STUDYOFHIGH DIRECTIVITYIN LOWPERMITTIVITY METAMA TERIALSLABS FOR LEAKY -W A VE MODELS

Published By : Laxmi Book Publication

Abstract :

Investigation has been carried out on the directivity of grounded low–permittivity metamaterial slab structures that achieve highly directive broadside radiation. T wo–dimensional (2D) configurations excited by electric line sources are considered, adopting a scalar plasma–like dispersive permittivity for the metamaterial medium that suitably models a wire medium in the presence of a 2D electromagnetic field, with the electric field directed along the wire axes. The role of leaky waves in producing the high directivity attainable with such structures is illustrated by comparing it with a simple ray–optic model for the radiation mechanism.
