A waveguide is a structure which guides energy waves, such as electromagnetic waves or sound waves. Waveguides are metallic lines, similar in fashion to transmission lines, which are used at microwave frequencies. Unlike coaxial cable which is also a transmission line, there is no center conductor within the waveguide. Signals propagate within the confines of the metallic walls that act as boundaries. The signal propagation is confined by total internal reflection from the walls of the waveguide. | A waveguide is a structure which guides energy waves, such as electromagnetic waves or sound waves.
