Scattering of a plane electromagnetic wave by two semiinfinite dielectric slabs
Abstract
The scattering problem for a plane wave by two semiinfinite dielectric slabs (the permittivities epsilon 1 and epsilon 2) is formulated in the simultaneous WienerHopf equations, and a formal solution is obtained. The approximate calculation is made in order to obtain physical quantities. The far field is calculated using the saddlepoint method for thin slabs. The power of the surface wave excited at the slab discontinuity is calculated by means of the parameters of the incident angle and epsilon 2. The number of the surface wave modes is found to increase with the slab thickness.
