Radio-frequency Forced Oscillations in Non-uniform Plasmas†

Abstract
A wave equation and associated equations is derived for periodic forced oscillations in a collision free plasma. This set of equations is rather complicated and small signal approximations are derived, which are applicable to plasma confinement problems. One approximation is applied to the case of a fast E 0 travelling wave in plasma and its behaviour is shown to be markedly different from the well-known case of an E 0-wave at cut-off. Some difficulties with small signal theories are indicated and the need for further clarification pointed out.
