The report briefly summarizes the effort directed towards understanding of electromagnetic radiation propagation and scattering in inhomogeneous media. Models are postulated for antenna radiation through inhomogeneous dispersive media, weakly ionized gases, and gyroelectric plasmas. Analytical expressions are derived to describe the interactions. Effort was also directed toward defining the scattering ability of these same media. A new theory for calculating antenna radiated power was formulated which eliminated the discontinuities obtained by conventional analysis. A rigorous solution was derived for the problem of shielding against high-intensity electromagnetic bursts EMP, at present however, the analytical description is quite idealized. The method of invariant imbedding was used to analytically describe the scattering capability of a jet stream. The description is very powerful in that the reflection coefficient can be found without knowing the wave functions within the stream. The present work is directed toward obtaining an understanding of the interactions between electromagnetic radiation and moving inhomogeneous media. Author
