Stimulated Brillouin scattering of an electromagnetic wave in a magnetoactive. dissipative multi-ion-species plasma

摘要

Stimulated Brillouin scattering of an electromagnetic wave is investigated analytically in adissipative magnetized plasma in the presence of negative ions. With an increase in the number of negative.ions (maintaining quasi-nmitrality). it iK found that the growth rate of ion-acoustic waves decreases very slowly up to 50% concentration (i.e. half of the total ionic contribution) of negative ions. further increase in the number density of negative ions beyond 50% results in a sharp fall in growth rate.
