Waveguide Definition: A material medium that confines and guides a propagating electromagnetic wave. A rectangular, circular, or elliptical metal pipe designed to transport electromagnetic waves through its interior. The transmitted waves are reflected by the walls of the waveguide.

The pictures show two rectangular waveguide tubes and a double ridge waveguide. Flexible waveguide are not yet shown.
A waveguide is a microwave transmission medium that is used starting after around 1000MHz, replacing cabled transmission line because of the increasing loses incurred within the cable. In fact a waveguide functions better at higher frequencies and has a lower frequency cut-off; while coaxial cable operates better at lower frequencies and has a upper frequency cut-off.
The term hollow conductor is used when comparing a waveguide to a coaxial cable, with a center conductor. Waveguides have no losses due to radiation, while cabled interfaces do. Although a shielded coaxial line also does not radiate energy, the losses incurred by the solid dielectric negate the fact that losses are not due to radiation. Air is the most common dielectric used with wave-guides.
