Abstract : The report presents the technical basis used in the development of a computer program for assessing the effects of ambient and disturbed daytime and nighttime ionospheres on the reflection and transmission of radio waves in the 10 to the 10th power to 0.001 Hz frequency range. The ionospheric models and electromagnetic theory used are described, certain limitations are discussed, and the parameters and equations used are summarized. A number of results obtained from the program are presented in graphical form. From these, the existence of height-dependent pass bands, stop bands, and conduction bands in the ionosphere is evident. Also shown are reflection levels and two-way reflection losses. These results provide useful understanding of ionospheric wave propagation, and serve as background material. (Author)
