Hybrid Analysis of Structures Composed of Axially Symmetric Objects

A hybrid method for the scattering problems in shielded and open structures is presented. The procedure is based on the combination of body-of-revolution involving finite-element methods with impedance matrix formulation and the mode-matching technique, which can be utilized for the analysis of structures with axially symmetrical scatterers. In order to confirm the validity and efficiency of the proposed approach, a few examples of electromagnetic field scattering in open and waveguide structures are analyzed. The results cohere with those obtained by commercial software.
