Decomposition peculiarities at the modeling microwave devices with discrete spatial spectra

Abstract

Using the technique of generalized scattering matrices is convenient for solving complicated problems of scattering on the basis of the decomposition principle. While modeling key blocks by the momentum method at essentially different dimensions of the channels, one can increase the calculation accuracy by means of decomposition of the element into two virtual ones. This idea is realized here by accounting for the character of the momentum method solutions more completely. The author considers the well-known effect of resonant matching by the example of the resonator formed of a section of plane parallel waveguide bounded by two thin inductive diaphragms with very small coupling slot.
