Mathematical approach, allowing calculating the basises of electromagnetic unhomogeneities of arbitrary cross section, is applied to solving the scattering problem for multi-slot iris in circular waveguide. Control of the coupling between the waveguide and the iris via a changing the iris profile is shown. Multi-slot iris with not equal slots forming rejection response is proposed.References
