Electrodynamic analysis of rectangular waveguides with L-Shaped Septa

The methods of electrodynamics calculation and PC modeling of the electromagnetic field structure of TE- and TM-waves are derived. The problem is solved by the method of partial regions including field singularity at the edge. Using this program modules we can modeling on the PC electromagnetic field structure of TE- and TM-waves in three types of waveguides: Rectangular Waveguide with Two L-Shaped Septa, Rectangular Waveguide with Two Antipodal L-Shaped Septa, Rectangular Waveguide with four L-Shaped Septa. The cutoff wave numbers, the electromagnetic field structures of different types of TE- and TM waves of the waveguide are calculated.
