WAVE GUIDES
The part of a microwave system that established the theory of operation for all of the other devices is the interconnecting hardware called wave guide. The conductors of microwave energy constitute a departure from conventional cables in that they resemble a coaxial cable with the centre conductor removed, Fig. 50.4. Microwave energy is carried through the waveguide by reflection along its inside walls.
