Abstract
THE problem associated with the applications of radio waves to communication, location or navigation is to generate high-frequency alternating currents and convey them from the source to an antenna system which radiates the waves into space. The connecting link between the source and the radiator is termed a transmission line, and for moderately high radio frequencies may comprise a system of two parallel wires, or a coaxial cable or some elaboration of these. At the very high frequencies corresponding to wave-lengths less than a few centimetres in length, this transmission line system takes the form of hollow conductor of circular or rectangular cross-section termed a wave guide. The two books under review deal respectively with transmission lines and wave guides as used in modern radio frequency technique.
