English version.Aimed principally at practising electrical and electronic engineers, this book presents a comprehensive , structured study of the propagation phenomena occurring between a transmitting and a reception antenna, one or both of which is in the terrestrial environment.Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another, or into various parts of the atmosphere. As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering.Understanding the effects of varying conditions on radio propagation has many practical applications, from choosing frequencies for international shortwave broadcasters, to designing reliable mobile telephone systems, to radio navigation, to operation of radar systems.Very good book and good unclipped jacket. Letters are written on the front cover, marks on the back, there is slight foxing to the cover edges.
