Planar EBG on electrically and magnetically anisotropic slab

Abstract

[1] A full-wave analysis of planar electromagnetic band-gap (EBG) on anisotropic slab, which is characterized simultaneously by both nondiagonal second rank [e] and [m] tensors, is presented. The analytical procedure is based on Galerkin's method applied in the spectral domain, and the spectral dyadic Green's function for the considered structure is formulated based on Maxwell's equations directly. A kind of Uniplanar Compact EBG (UC-EBG) on anisotropic slab is computed efficiently, and the influence of the principal axes' rotation in the transverse plane on their band structures are studied for several slab materials.
