Gaussian wave beam scattering on reflect phased antenna array with shorted rectangular cross-section waveguides

The investigation of Gaussian wave beam diffraction on reflect array with shorted rectangular waveguides is produced. The cases of normal and oblique incidence of wave beam on reflect arrays are considered. The dependence of energy losses of specular beam from the length of the shorted waveguides and wavelength is studied. The two-dimensional patterns of specular and not specular beams are present.
