Abstract : One of the ways in which the detailed shape of the charged particle velocity distribution function in a plasma may manifest itself is in the dispersion characteristics of plasma wave propagation. Indeed, several phenomena, e.g. Landau damping, cyclotron damping, and cyclotron harmonic waves, can only be predicted from a microscopic theory of the propagation. In recent years, experimental agreement with theory based on the Vlasov equation has been demonstrated for such phenomena with a high degree of accuracy for Maxwellian plasmas, in the small-signal propagation limit. This paper reviews some of the work already carried out, and then discusses some likely future developments in the comparison of theory and experiment for situations where the small-signal approximation breaks down. Some relevant results on wave/wave interaction are described. (Author)
