Plane wave scattering by slots on a ground plane

The problem is formulated in the following statement. The unlimited space is divided by the indefinitely thin perfect conducting screen into two areas V/sub 1/ and V/sub 2/ (Fig. 1). The area V/sub 1/ with parameters /spl epsiv//sub 1/, /spl mu//sub 1/ contains stimulating sources, located in volume Vj. Area V/sub 2/ with parameters /spl epsiv//sub 2/, /spl mu//sub 2/ does not have stimulating sources. The area V/sub 1/ borrows the whole top half-space and is limited by a surface S/sub 1/, the area V/sub 2/-limited by a surface S/sub 2/. The areas are connected by two parallel cracks of S/sub 0/ width each, divided by strip conductor. It is necessary to define scattering field. The decision of a problem will be carried out using the method of integral equations. Initial integral equations are decided numerically using Krylov-Bogolyubov method. As a result of integral equations an aperture of a crack is defined which is used for finding the angular radiation pattern. Patterns of the slot were calculated for different geometry parameters, space parameters and /spl phi/.
