Abstract

A consistent description of the propagation of an electromagnetic field perturbation through a succession of cut-offs and mode conversions in a Vlasov plasma is derived. Whereas the quantitative description confirm some qualitative expectations, the results about the transmitted energy are less obvious. In particular, the transmitted energy is larger when the direction of the incident wave is such that the cut-off is encountered first, than for the opposite direction. Moreover, the transmission coefficients for forwards and backwards waves strongly depend on the plasma parameters.
