Excerpt from Ionospheric Radio Propagation The considerations brought out in chapters 7 and 8 are employed practically in chapter 9 to enable the calculation of the lowest useful high frequency that may be used for communication over certain paths at certain times employing a given amount of power, and also the calculation of the inverse quantity, i. E., the lowest required radiated power to permit communication for specified conditions and frequencies. Several examples of the calculation of the quantities involved are given, and the necessary charts and data for these calculations are presented.

Excerpt from Bibliography on Ionospheric Propagation of Radio Waves The material is arranged alphabetically by the first author's name, and chronologically under each author. An author index is pro vided for the purpose of identifying works of added (i. E. Second or third) authors where teams have cooperated in writing an article. A subject and place outline, and subject index are also provided in order to give the reader an idea of the scope of the subject material involved. Obviously, with such a large total number of items on a fair narrow range of subject matter, there will be too large a number of re terences on some subjects no matter how noble an effort is made to sub divide the material under each heading.

Excerpt from Long-Range Propagation of Low-Frequency Radio Waves Between the Earth and the Ionosphere Instead of considering the problem in spherical geometry, we shall demonstrate that the error incurred by treating the earth as a plane and the ionosphere as a plane stratified medium is negligible for the parameters we shall calculate.

Excerpt from Ionospheric Propagation of Plane Waves: August 1953 The propagation of plane waves in a stratified ionosphere is considered. It is shown that the construction of 'true' characteristic waves depends upon the diagonalization of a matrix by a Loewy transformation. For a homogeneous ionosphere this construction can always be carried out explicitly. For the general case we obtain the wave solution in terms of characteristic waves which have the properties usually attributed to characteristic waves in magneto-ionic theory. In addition, the interaction between these waves is made clear by the introduction of continuous reflection and transition coefficients. Ordinary and extraordinary wave-reflection levels are shown to be points at which the elementary divisors of a certain matrix become non-simple. Complicated expressions are obtained from which ionospheric reflection and transmission coefficients may be obtained explicitly. Explicit solutions are obtained for normally incident waves with an oblique earth's magnetic field and for oblique incident waves with a vertical earth's magnetic field.

This classic book presents the theory and practice of ionospheric radio propagation of plane waves, and is an invaluable reference for scientists and engineers working in the field of telecommunications. The book covers both the theoretical and experimental aspects of ionospheric propagation, and includes detailed discussions of the factors that affect ionospheric absorption, reflection, and refraction of radio waves. It also includes many practical examples and applications of ionospheric propagation, and provides readers with a solid grounding in the fundamentals of this important field.
