Abstract
Abstract A compact, stable microwave resonator employs a solid quartz cylinder coated on its surface with a material having good electrical conductivity at very high frequencies. The coating is made up of an inner layer of chromium much thinner than the skin depth of microwave currents and a thick outer layer of a metal of high conductivity for microwave currents. The coating has a pair of diametrically positioned apertures for coupling microwave energy to hollow wave guides extending radially from the cylindrical conductive surface. The waveguides have end faces matching the curved conductive surface and each has a mounting frame with arms extending partly around the cylindrical surface. Opposed flanges on the arms cooperate with resilient fasteners to clamp the waveguides in cooperative positions on opposite sides of the cylindrical surface.
