Abstract:

Non-linear coupling between slow and fast waves in a circular waveguide partially filled with a plasma was studied experimentally. The waveguide was short-circuited to form a resonant cavity. A slow, symmetrical wave was launched on the plasma column and propagated into the cavity. By feeding pump power into the TM sub 010 resonant mode of the cavity a non-linear coupling between the slow wave and the TM sub 011 resonant mode could be achieved when the frequency of the slow wave was equal to the frequency difference between the two resonant modes. With a pump power of 1 watt an over-all coupling coefficient of the order of - 40 dB was obtained. Author
