A flat reflector having retroreflection characteristics is presented based on transformation electromagnetics. The retroreflector is designed with a distributed full-tensor anisotropic metamaterial. Its retroreflection operations are confirmed by circuit simulations based on the equivalent circuit model of the distributed anisotropic metamaterial.
Planar distributed full-tensor anisotropic metamaterials for cloaks of invisibility based on transformation electromagnetics are proposed. The proposed metamaterials are composed of nonresonant transmission lines and are advantageous in full control of the off-diagonal components of the permeability tensor as well as broadband and low-loss characteristics. The explicit design formulas for the metamaterials...
In this paper, recent works on transmission line metamaterials for transformation electromagnetics are overviewed. The concept the transmission line approach using physical equivalent circuit model for anisotropic materials is introduced. The validity of the model is confirmed by demonstrations of an invisibility carpet cloak design and circuit simulations. In addition, potential applications of the...
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...
We present a physical equivalent circuit model for 2D full-tensor anisotropic materials to realize transmission-line-based invisibility cloaks. With the equivalent circuit, it is shown that the equivalent circuit expresses well with full-tensor anisotropic material and diagonal and off-diagonal components of the permeability tensor physically correspond to the self- and mutual inductances per unit...
