Abstract :
On the base of rigorous numerical models multiaperture irises in a rectangular waveguide have been investigated in order to obtain new electromagnetic features with the aim to use them in waveguide filter design. Rigorous models for a multiaperture iris has been developed on the base of the scattering matrix formulation. S-matrix of key-building block of the double-plane multifurcated discontinuity, has been obtained by solving appropriate diffraction problem by known mode-matching technique of the moments. The number of basis functions of the waveguides, providing required accuracy in numerical studies, has been chosen according to their cross-section dimensions
