Abstract
A device for absorbing resonances in a large circular cavity such as a microwave rotary joint that utilizes a horizontally positioned resonance absorber positioned in the balun cavity to absorb the resonances or undesired modes. The resonance absorber forms a folded slot with a resistor across its arms to interrupt the circumferential flow of current in the rim of the cavity without affecting the normal desired mode.
