In this paper, analytical modeling of natural modes is proposed for the rapid and accurate analysis of various high impedance surfaces (HIS) composed of dense grids of frequency selective surface (FSS) elements printed on an electrically thin grounded dielectric slab, and on a wire media slab. The dynamic model of the grid is based on the homogenized surface impedance, which is obtained from the full-wave solution in a spectral domain. The homogenization model of mushroom-like HIS structures consists of local model of the wire media slab (based on the epsilon-negative (ENG) approximation) and dynamic model of the grid. This enables one to accurately capture the physics of surface-wave propagation in the resonance band of HIS structures within the limits of homogenization.

Abstract

In this paper, analytical modeling of natural modes is proposed for the rapid and accurate analysis of various high impedance surfaces (HIS) composed of dense grids of frequency selective surface (FSS) elements printed on an electrically thin grounded dielectric slab, and on a wire media slab. The dynamic model of the grid is based on the homogenized surface impedance, which is obtained from the full-wave solution in a spectral domain. The homogenization model of mushroom-like HIS structures consists of local model of the wire media slab (based on the epsilon-negative (ENG) approximation) and dynamic model of the grid. This enables one to accurately capture the physics of surface-wave propagation in the resonance band of HIS structures within the limits of homogenization.
