Wave Propagation in Drifting Isotropic Warm Plasma

This is the authors' abstract. We don't add key points for this paper.

The electro‐magneto‐plasma‐gas‐dynamics (EMPGD) equations are given for the warm, compressible electron gas, with no magnetostatic field, drifting with a constant velocity, by taking into account the fluid dynamics variables of the electron gas and using small‐signal theory. Assuming harmonic time variation, an algebraic equation is found for the refractive index of the plasma characteristic waves. Particular cases are discussed and compared with previous results.
