Abstract: In a resonant cavity which has multiple modes of resonance within a desired frequency band, certain undesired modes are selectively detuned out of this frequency band, leaving a single desired mode within this band. This is accomplished by the insertion of elongated conductive members into the cavity, so placed and oriented that they cause strong field distortion and detuning of the undesired modes, but cause little effect on the field pattern of the desired mode with little detuning. In the case of a cylindrical cavity operating in a TE011 mode, coupling can be accomplished through an end wall of the cavity substantially without mode interference effects, permitting more economical methods of construction. The principle has been applied to single cavity and multiple cavity resonators and wave filters.
