Technical Note Coping with Hidden Spurious Harmonic Modes in the Design of Low Pass Corrugated Waveguide Filters Hidden spurious harmonic modes in corrugated waveguide filters are investigated from both theoretical and practical points of view. It has been found that multiple mode couplings occurring at more than one place...
