Electromagnetic diffraction problem on dielectric body located in rectangular waveguide and consisted of two layers is considered. The analytical solving of Maxwell`s equations in case of filling of two section of the waveguide is obtained. Numerical results for solution of integro-differential equation by collocation method are presented.

electromagnetic diffraction problem, analytical solution of diffraction problem, collocation method.
