Abstract

In this paper an authors´ hybrid method is applied to the analysis of waveguide junctions loaded with arbitrary configuration of axially-symmetrical posts. The method is based on a combination of finite-difference frequency-domain method and mode-matching technique. In our approach each scatterer is treated as an effective circular cylinder represented by impedance matrix defined in its local coordinate system. In order to obtain the scattering parameters of an arbitrary configuration of objects in global coordinate system an analytical iterative scattering procedure (ISP) is utilized. The validity of the proposed approach is verified with the analytical approach and commercial software.
