The transmission coefficient of a wave barrier for electron plasma waves has been studied experimentally as a function of the potential drop at the barrier and as a function of its spatial profile. The transmission coefficient increases with increasing potential drop, in accordance with the theory of V. V. Lisitchenko and V. N. Oraevskii, )Dokl. Akad. Nauk SSSR 201, 1319 (1971) (Sov. Phys. Dokl. 16, 1074 (1972))). The spatial damping rate of the wave, evaluated from a comparison of the theoretical and experimental behavior, agrees satisfactorily with the experimentally observed damping of the wave which has ''crossed'' the barrier. Extenion of the potential drop into the plasma surrounding the barrier reduces the barrier transmission. The transmission of the barrier is governed primarily by the potential profile in the plasma ahead of the barrier. Possible reasons for this effect are discussed. (AIP)
