Abstract :
Theoretical and experimental studies of spurious and extra waveguide oscillation in crossed-field devices are described. Theoretically the existence is shown of spurious and extra waveguide oscillations in wide band (from some cycles to dozen gigacycles), and amplitude-from some millivolts to hundred volts. We studied two oscillation processes: ion and electron. Experimentally these oscillations are detected in the output spectrum, and emission from cathode junction is found. Thus crossed-field devices influence EMC.
