Physical equivalent circuit model for 2D full-tensor anisotropic metamaterials

A physical equivalent circuit model for 2D full-tensor anisotropic materials is presented. From the circuit analysis, it is shown that the diagonal components of the permeability tensor directly correspond to the self inductances per unit length, and the off-diagonal components physically correspond to the mutual inductance per unit length. A 2D carpet cloak is designed and its operation is confirmed with circuit simulations. The complex voltage distributions agree well with those of corresponding specular reflection cases, and validity and usefulness of the proposed equivalent circuit are confirmed.
