ABSTRACT:
A one-piece gasket is used between millimeter waveguide sections to prevent energy leakage from the joint. The gasket consists of an electrically conductive elastomeric ring filled with metallic particles, a conformable metallic inner shield on the inner periphery of the ring, and a conformable metallic outer shield on the outer periphery of the ring. The gasket is conveniently prepared by casting the filled elastomer in place between the shields.
