Cw. Peters et al., TIME-FREQUENCY ANALYSIS OF MODULATION OF HIGH-POWER MICROWAVES BY ELECTRON-BEAM VOLTAGE FLUCTUATIONS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 58(5), 1998, pp. 6880-6883
This paper applies a time-frequency analysis to the output signal from
a coaxial gyrotron oscillator. It is shown that the voltage fluctuati
ons on the diode can be directly correlated to the frequency modulatio
n on the rf output. A simple analytic theory is constructed to explain
this correlation. This technique, properly extended, is expected to o
pen up a new way to investigate pulse shortening, mode competition, no
ise and unwanted frequencies in rf generation. [S1063-651X(98)11211-4]
