Abstract :
The electro-magneto-plasma-gas-dynamics (EMPGD) equations are summarized, based on the single-fluid, continuum-theory, macroscopic plasma-dynamics theory. The derivation of the three-dimensional wave equations for linearized, isotropic, compressible, warm plasma is reviewed. In accordance with a well-used approach in the theory of elasticity, the wave equations are separated into the acoustic ((longitudinal) and the electromagnetic (transverse) waves.
