An accessible student–oriented approach to radiowave propagation Propagation–the process whereby a signal is conveyed between transmitter and receiver–has a profound influence on communication systems design. Radiowave Propagation provides an overview of the physical mechanisms that govern electromagnetic wave propagation in the Earth?s troposphere and ionosphere. Developed in conjunction with a graduate–level wave propagation course at The Ohio State University, this text offers a balance of physical and empirical models to provide basic physical insight as well as practical methods for system design. Beginning with discussions of propagation media properties, plane waves, and antenna and system concepts, successive chapters consider the most important wave propagation mechanisms for frequencies ranging from LF up to the millimeter wave range, including: Direct line–of–sight propagation through the atmosphere Rain attenuation ...
