Wave diffraction on diaphragm of window type with thin layer of magnetodielectric

Abstract

The strict analysis of wave diffraction on thin diaphragms of a type rectangular is necessary for development of an element base of microwave devices. Here solving of these three-dimensional tasks is extended to the case of presence of boundaries of isotropic media near to metal discontinuity of window type. Build-up of algorithms consists in considering of two crossed one-dimensional obstacles and next passage to the limit on their approaching before merging in one two-dimensional (with the added now dielectric inclusion). The infinite systems of the linear algebraic equations are obtained with two-dimensional group of sought values (amplitudes of excited waves). The measures are undertaken on simplification of algorithms. One of the practical applications of the apparatus is developed here-clearing up of details of a discrepancy of the theory and experiment in a problem of matching of dielectric vacuum windows.
