New physical effects at an air pseudochiral omega interface: Surface polaritons and proper leaky-modes.

Surface polaritons are guided electromagnetic waves propagating along a single interface, with the amplitude of the field decreasing along the direction that is normal to the interface. These modes can propagate along interfaces separating a conventional (double-positive) isotropic medium either from a single-negative or from a double-negative medium. They were also found to propagate along isotropic–uniaxial and isotropic–biaxial interfaces. In this paper we show, for the first time, that surface polaritons can also occur at an interface between air and a pseudochiral omega medium. It is also shown, furthermore, that proper leaky-modes can also exist in this special type of isotropic–bianisotropic interface—a completely new physical effect for a single interface between two lossless media. © 2006 Wiley Periodicals, Inc.
