Abstract


On the basis of the projection method the rigorous solution of the basic wave Н10 diffraction problem on a joint of a regular and non-regular waveguides with a dielectric plate placed parallel to narrow impedance walls is presented. The problem is solved by the method of partial areas. For each of three dedicated areas subject to boundary conditions on the waveguide walls solution of Helmholz equation is put down in the form of cross-section eigenfunction. For a non-regular area including impedance walls and a dielectric plate the solution of Helmholz equation leads to a dispersion equation from which the propagation constants in the area under investigation is determined. Meanwhile, the influence of the impedance walls is considered by means of the Leontovich boundary conditions.
