Abstract

DB boundary conditions require vanishing of normal components of electric and magnetic flux density vectors on the boundary surface. In this paper, we present a free-space simulation analysis of the unit-cell structure proposed for the realization of a metamaterial exhibiting DB boundary conditions. From numerically calculated reflection and transmission parameters all components of the effective permittivity and permeability tensors, characterizing the DB material, are retrieved both in the axial as well as in the orthogonal directions to the metamaterial boundary. Such effective constitutive parameters are extracted using S-parameter inversion technique for obliquely incident wave.
