| Abstract: | A method of mode content analysis in oversized waveguides basing on intensity measurements in a few cross sections is suggested.
The method is based on iterative synthesis of phase fronts of the radiation measured in a few cross sections of an oversized
waveguide. The phase reconstruction 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 impedance corrugation
of the walls 8]. |
