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.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.This work is in the "public domain in the United States of America, and possibly other nations.
