Efficient Hybrid Finite Elements - Modal Expansion Method for Microstrip-To-Waveguide Transitions Analysis

Abstract

The characterization of a microstrip-to-waveguide microwave transition is performed via the application of an efficient Finite Element Method/Hybrid Modal Expansion. The method requires the knowledge of a modal expansion at each junction port. This expansion is known in the waveguide and is numerically computed in the microstrip region via the Finite Element Method again.
