A focussed Gaussian beam generated by an 83-GHz, 15-kW CW Gycom, Ltd. gyrotron is being applied to the processing of ceramic materials at the Naval Research Laboratory. Available microwave power densities of ≥1 kW/cm2 enable rapid, localized heating of ceramic coatings and joints, provided adequate microwave-material coupling is achieved. This paper describes theoretical and experimental studies of microwave beam coupling to and propagation in multi-component ceramic systems corresponding to joints and coating configurations. Localized coupling enhancement using mixtures of ceramic and metal powders has been investigated. Techniques for minimization of reflection (important in a single-pass beam system) and beam polarization effects will be discussed, as well as the results of experiments designed to enhance heating rates based on these effects.
