This volume primarily deals, in simple language, with function and behavior of radio waves, and construction and function of antennas. It is a must have for the bookshekf of any science or electronics enthiusiast.

PROPAGATION means "movement through a medium." In this case, the science of sound, light and radio waves moving through antennas and waveguids, the earth, sea, space, and atmosphere.

It begins with some basic physics of light and sound waves , then moving into Doppler Effect, Radio Waves and Transmission Lines.

Lessons include principles and common applications of a full range of radio frequency bands from the long range VLF in the 3-30 KHz, through LF, MF, HF, VHF, UHF, SHF, and 300GHz EHF.

Finally, an entire chaper is dedicated to an extensive discussion of the construction and function of antennas, from simple aerial long wires, to phased sattelite arrays.
