LATERAL WAVES ON DIFFUSE DIELECTRIC INTERFACES
Abstract
In the past the lateral wave has been investigated for the case of a sharply bounded transition layer and a layer with a linear velocity variation. The interpretation of the lateral wave given in these instances cannot be extended to an arbitrary smooth layer, and in many cases, the exact nature of the lateral wave contribution becomes unclear. It is our purpose to clarify these matters and to present the characteristics of lateral wave propagation on a layer of arbitrary variation. The models employed can simulate an inhomogeneous plasma having a number density profile, n(z), which varies continuously between two homogeneous half spaces. An integral representation for the scattered field in the optically denser half space is found and evaluated asymptotically in the high frequency limit. This asymptotic evaluation is carried out in two parameter ranges: first, when the layer is thick compared with wavelength; and second, when the layer thickness is arbitrary but the observation point's distance along the interface is large compared with layer thickness.
