DEFINITION

Classification: 333/135

Including waveguide element:

(under subclass 134) Subject matter wherein the long line

element is of the type having a magnetic or electrical component extending in the direction of propagation.

(1) Note. WAVEGUIDE: A transmission device designed to propagate electrical waves having an electric or magnetic field component extending in the direction of propagation. The wave-guide may be a hollow dielectric or metal tube or a solid dielectric rod, the wave energy being propagated along the interior of the tube or rod and confined by the walls of the tube or rod.
