In order to circumvent power limitation problems in lumped circuit elements or devices using surface properties, work on analyzing wave propagation in nonlinear ferroelectric media is being considered. Attempts to solve nonlinear vector wave equations are being tried. Work on trying to understand and analyze the nonlinear properties of a microwave gas discharge was started. The simple theory of a gas discharge commonly employed is being studied to see if it can be used to predict approximate results. The pulsed, x-band, gas discharge multiplier was scaled down to be tried with a 3(1 watt CW, 8.6 mm drive. The harmonic power conversion ratios were lower than expected, and some new problems of damage to the discharge post occurred. Various circuit configurations, using resistive diodes to simulate crystals, were studied for frequency conversion characteristics. The problems of matching the driving source and obtaining maximum converted power were investigated. Increased effort was placed on the synthesis of microwave frequency multiplying circuits. A dual resonant cavity which simultaneously resonates at frequency f/sub o/ and Nf/sub o/ is being studied. A sensitive, wave load calorimeter was designed for work in the range 60 to 90 kmc/s which can probably be scaled to 140-220 kmc/s. (For preceding period see AECU-4199.) (W.D.M.)
