Analysis of eigenmodes in rectangular waveguide with two antipodal L-shaped septa
The method of electrodynamics calculation and PC modelling of the electromagnetic field structure of TE- and TM-waves in air filled lossless rectangular waveguide with two antipodal L-shaped septa is derived. The problem is solved by the method of partial regions including field singularity at the edge. The cutoff wave numbers, the electromagnetic field structures of different types of TE- and TM-waves of dominant mode of the waveguide are calculated.
