Waveguide

Structure that guides waves, such as EM or sound waves. Waveguide a system of conductive or di-electric materials in which boundaries and related dimensions are defined such that electromagnetic waves propagate within the bounded region of the structure. Although most waveguides utilize a hollow or dielec-tric filled conductive metal tube, a solid di-electric rod in which the dielectric constant of the rod is very much different from the di-electric constant of the surrounding medium can also be used to guide a wave.
