Origin of surface modes in nonconducting metamaterials: from the viewpoint of bound charges.

Abstract

Conventional optical modes are supported by the total internal reflection occurring due to refractive index difference. Surface modes guided through an interface seem to have a different origin from them because they are supported by the difference in the signs of constitutive parameters of two media comprising the interface. Here, we propose that these… (More)
