Waves in a Two-Temperature Plasma with Periodic Electric Field

Abstract

Starting from two-fluid model hydrodynamic equations, a dispersion relation is obtained for wave propagation through a two-temperature plasma perpendicular to the direction of an external electric field E₀ cos ω₀t and several excitation conditions are deduced for small values of the parameter ε=ekE₀⁄m_eω₀², in which k is the wave-number and e, m_e are the charge and mass of an electron.
