INVESTIGATION OF MICROWAVE DUPLEXER SWITCHING MECHANISMS.
Abstract
Accoustic waves produced by an intense, localized RF breakdown are used to measure chemical and thermal effects resulting from gas breakdown. Pulsed RF breakdown in oxygen produces ozone. By measuring the velocity of propagation of sound waves in such an ozone-oxygen mixture the percentage of ozone present can be calculated. The rate of decay of pzone can be determined by making this measurement at various times after the cessation of the 1 microsec RF pulse. These acoustic waves are observed to propagate at a velocity slower than the speed of sound in mixtures of xenon with helium, oxygen, nitrogen, and neon. Second harmonic power is produced in a pulsed discharge afterglow plasma and found to display typical behaviour. Microwave power at a second harmonic frequency is also generated by the nonlinear interaction between an electromagnetic wave and an electrically driven shock wave. (Author)
