Abstract: A modular microwave choke assembly for attenuating microwave energy along a rotating shaft. The choke assembly generally includes a plurality of choke rings connected together, the plurality of choke rings positioned and shaped to surround a portion of a shaft that extends out of a microwave chamber, wherein each choke ring creates a high-impedance zone adjacent to the portion of the shaft surrounded by each choke ring. The plurality of choke rings are spaced apart from each other along the shaft. A plurality of gaps are formed between the plurality of choke rings, along the shaft, wherein the gaps are created by the spaces between the plurality of choke rings. The choke rings and the gaps create alternating high-impedance and low-impedance zones along the shaft that attenuate microwave energy.
