Substrate-induced bianisotropy in metamaterials

arXiv:1006.1159 · doi:10.1063/1.3486480

Abstract

We demonstrate that the presence of a supporting substrate can break the symmetry of a metamaterial structure, changing the symmetry of its effective parameters, and giving rise to bianisotropy. This indicates that magneto-electric coupling will occur in all metamaterials fabricated on a substrate, including those with symmetric designs.
