Abstract : The complex dielectric equations describing the interaction of an electromagnetic wave with an ionized medium are derived from a basic consideration of electromagnetic wave propagation and the motion of a free electron in a polarized electric field. The equations consider a plane, transverse vave propagating into a dielectric medium of arbitrary, but uniform, density. The effect of electron collision damping is considered. Interface losses are discussed. Graphs and tables, obtained with digital computation, indicate the variation of attenuation and phase shift per unit path length with the applied microwave frequency for various electron densities.
