Numerical simulation of a complete cavity coupled with bridge devices requires unattainable computing resources. In this regard, the analytical representation for the coupled non-uniform system based on multimode approximation is considered. The analytical model for a system consisting of a short CDS section coupled with a rectangular waveguide segment is presented. The model is calibrated by direct numerical simulation. A generalization allowing parameters selection for the new CDS cavity sections and bridge devices coupling based on the presented model is proposed.
