註釋

A kinetic theory of electrostatic cyclotron waves in a single component plasma slab of density n sub o(x) immersed in a uniform magnetic field B sub o z is presented. The space charge electric field Eo(x)x in such a plasma modifies the single particle gyrofrequency causing the upper hybrid frequency to have the value sq. rt. ((Omega sub 1) squared + (omega sub p)squared). Finite Larmor radius effects introduce a velocity dependence into the single particle gyrofrequency, leading to energy transfer to the particles located at the resonant layers. This energy transfer mechanism is operative even when sub f = O. Another nonzero Larmor radius effect is the appearance of thermal modes which are the analogs of Bernstein modes of neutral plasmas. When driven by an external capacitor plate antenna, these modes exhibit behavior similar to Tonks Dattner resonances.
