Interaction between the open ends of the wide-side multimode waveguide radiators with dielectric filling

Mutual (between modes) active and reactive conductivities of an open end of wide-side rectangular waveguide, filled with ideal dielectric are investigated, also the interaction between waveguide radiators is studied. The finite antenna arrays consisting of open ends of rectangular waveguides can be investigated sufficiently easily by calculation of mutual influence between two waveguide radiators.
