Abstract :
Previous work on field/voltage analysis in microwave filters is extended to cover the critical case of harmonic filters with complex geometry. It is shown here that filter power handling capability can be predicted with a fully analytical method, even for complex waveguide devices such as evanescent-mode ridged and waffle-iron filters. Very good agreement with numerical and measured data is obtained.
