Radio Propagation Fundamentals*
Bell System Technical Journal, 1957The engineering of radio systems requires an estimate of the power loss between the transmitter and the receiver. Such estimates are affected by many factors, including reflections, fading, refraction in the atmosphere, and diffraction over the earth's surface.

The Propagation of Radio Waves
1985This book is concerned with the ionosphere and the magnetosphere, and the theory of their effect on radio waves. It includes accounts of some mathematical topics now widely used in this study, particularly W. K. B. approximations, Airy integral functions and integration by steepest descents.

The propagation of radio waves
Institution of Electrical Engineers - Proceedings of the Wireless Section of the Institution, 1926The paper gives the results obtained from a systematic study of the received intensities of various long-wave transmitting stations at four receiving stations over a period of nearly two years.The weekly averages of the results are studied, and it is shown that they are inconsistent with any law of steady decay.
