Abstract

The problem of electromagnetic waves diffraction by a system of pass-through resonators in a rectangular waveguide coupling by diaphragms with resonant slots was solved by the generalized method of induced magnetomotive forces (MMFs). A distinctive feature of the solution is characterized by using approximating functions defining magnetic currents in the slots obtained from solutions of current integral equations by the asymptotic averaging method. Multi-parameter studies of electrodynamic characteristics of such structures have been carried out. The comparison of numerical results with experimental data is presented.
