Analysis of the characteristics of the radiation from the open end of an oblique waveguide filled with a limitless dielectric plate

In the present work we consider the mechanism of interaction of the edges of two parallel half-planes separated by a dielectric layer unbounded on both sides. The analytical expressions for the characteristics of the radiation into a free space and for the amplitudes of the eigenmodes of the dielectric layer are obtained. A numerical analysis of the relationship between these characteristics and the geometric and material parameters of the structure is carried out.
