Abstract :
A novel computer-aided design (CAD) tool of complex passive microwave devices in rectangular waveguide technology is suggested. The multimodal variational method is applied to the full-wave description in the rectangular waveguides while the finite element analysis characterizes waves in the arbitrarily shaped discontinuities. The put forward hybrid approach is successfully applied to the full-wave analysis of complex irises CAD, thus improving CPU time and memory storage against several FEM-based commercial softwares.
