Leaky Waves in Metamaterials for Antenna Applications

Abstract

Focus was on investigating leaky waves and their excitation with multilayered metamaterials to enhance antenna performance: wave propagation along a grounded dielectric slab with double negative (DNG) materials, complex waves (leaky waves) changes with different material parameters, electric size (frequency and thickness) and loss, Sommerfeld integral path for evaluating fields accurately and efficiently, the radiation intensity and directivity of electric/magnetic dipoles over a grounded slab, and optimization of the directivity over the thickness and the constitutive parameters for antenna applications of interest to the Air Force.
