Appendix 11B: The First-Order Coupled
Differential Equations for Waves in
Inhomogeneous Warm Magnetoplasmas
*
The rst-order coupled differential equations for waves in temperate inhomogeneous mag-
netoplasmas are well known [1]. The extension of this method for the case of waves in
inhomogeneous warm magnetoplasmas is presented here. In this form, they are well suited
for solution on a digital computer by the Runge–Kutta method. The plasma is assumed to
be neutral and in equilibrium, and the motion of the ions is neglected. Taking E H
