Abstract

We have discovered that if input grating coupler is used to excite SEW the generated wave is differed essentially from SEW. This wave is conventionally named "pressed wave" by us. We examine the evolution of wave field with distance from input grating coupler and compare that with analogous dependence for SEW. It is shown that unlike SEW the intensity of pressed wave decreases not exponentially while it propagates along the surface. Also we have got that the pressed wave field profile is modified as it propagates along the surface.
