Abstract
A method of mode content analysis in oversized waveguides basing on in tensity measurements in a few cross sections is suggested. The method is based on iterative synthesis of phase fronts of the radiation measu red in a few cross sections of an oversized waveguide. The phase recon struction makes it possible to calculate field distribution as well as the mode content at any place of the waveguide. The method was tested in experiments with circular and rectangular waveguides with impedanc e corrugation of the walls [8].
