WAVE DIFFRACTION BY A THIN INCLUSION WITHIN A 2-LAYER WAVE-GUIDE

A process of diffraction of wave fields excited from the initial time by a monochromatic source by a thin inclusion within a two-layer mediu m is studied on the basis of further development of the factorization technique. The effect of the inclusion length and its submersion depth on scattered field intensity is analyzed. The research results taking account of the influence of layered medium plane boundaries generaliz e the known data(1,2) established for unrestricted media, as different iated from analytical relationships(3,4) obtained for the stabilized c ase for a more general model of scattering inclusion. The paper consid ers unstabilized processes of re-reflections and determines the charac ter of establishment of the diffracted field.
