  • Microwave components with a surface coating which imparts a very high RF loss
    Patent number: 4971856
    Abstract: To selectively and controllably increase RF surface power loss in microwave components, the component surfaces are overcoated with a suspension of conductive particles in a viscous binder of thickness less than a wavelength at the operating frequency. The binder is compounded so as to fire to a glassy matrix that is a durable, heat-resistant and vacuum-compatible dielectric. The metal particle size, which is selected to fit within the coating thickness, is preferably large compared with the RF skin depth of the conductive particles, but no smaller than one-quarter skin depth.
