Surface Electromagnetic Waves of Chiral Metamaterials Interfaces

抄録

We study the surface electromagnetic waves (SEMWs) of bi-isotropic chiral metamaterials. Phase diagrams of SEMWs are derived by combining the Maxwell equations and the constitutive relations which include chirality. Numerical results of the phase diagrams are presented for chiral metamaterial surfaces in the vacuum as functions of permittivity, permeability, and chiral parameters. It is shown that the chirality tends to change the localization lengths of SEMWs and strongly modifies the characteristic feature of the electromagnetic fields near the surface.
