Abstract : A mathematical model describing the propagation of electromagnetic energy through a stratified medium is developed. Applied to atmospheric conditions, it simulates propagation through atmospheric ducts. The final program used in the digital computer solution is given. Seven refractive index profiles representing normal, substandard, and superstandard conditions comprise the data. The results are valid within the area covered by the profile. Reflections from the earth's surface are omitted. The critical angle condition, constant phase fronts, and energy distribution are discussed. The results are presented as ray tracing diagrams and energy distribution diagrams. (Author)
