Nonlinear interaction is considered between a low-frequency whispering gallery mode and higher-frequency surface waves in a cylindrical plasma-filled cavity. It is shown that the steady-state intensity distribution of the whispering gallery and surface wave modes can depend on the azimuthal angle phi only for a specified cavity radius, and the maximum amplitudes of the whispering gallery mode must also lie in a discrete set. The decay of an intense whispering gallery mode of constant amplitude into two oppositely moving surface electromagnetic waves is discussed, and expressions are derived for the decay rate and threshold.
