Özet

Among the wave propagation problems, those connected with half-spaces bounded by sectionally homogeneous boundaries take important place because they are motivated by microwave applications. If the boundary are of three or more parts, then the problem results, very frequently, in functional equations involving unknown functions, say Ψ+ (v), Ψ- (v) and P(v), which are regular in the upper half, lower half and whole of the complex v-plane, respectively, except at the point of infinity. A local (non-homogeneous) perturbation on a two-part boundary, which is of extreme importance from engineering point of view, gives also rise to a problem of this type. The aim of the present paper is to establish a method which is based on the elimination of the unknown functions Ψ+ (v) and Ψ- (v) to obtain an integral equation of the Fredholm type for the entire function P(v), which can be solved rather easily by numerical methods. The functions Ψ+ (v) and Ψ- (v) are then determined by the classical Wiener-Hopf technique.
