The quantitative analysis of physical processes that occur during the excitation of planar and rectangular waveguides with an infinite flange, with a bending flange and an array of planar and rectangular waveguide radiators on an infinite plane and on an infinite wedge has been carried out. The analysis is based on coupling equations for the complex amplitudes of the electromagnetic field of array radiators and on equations for transfer admittances.

It is shown that the so-called “edge effect” in arrays consisting of a small number of radiators located on an infinite plane is naturally allowed for by the transfer admittance of its radiators. The influence of a bended plane (the edge of an infinite wedge) is also naturally allowed for by the “irregular” transfer admittance of array radiators (planar and rectangular).
