Class Information
Number: 343/783
Name: Communications: radio wave antennas > Antennas > Wave guide type (e.g., horn) > With internal-wave refraction means
Description: Subject matter wherein the wave guide contains a mass (usually dielectric) which freely passes radio waves, and which is shaped or positioned to delay or accelerate waves passing therethrough an amount which varies over the wave front for such purposes as focusing, changing direction, or changing the wave front as from circular to planar.
