Rectangular Waveguide -Animation
Rectangular waveguides are the one of the earliest type of the transmission lines. They are used in many applications. A lot of components such as isolators, detectors, attenuators, couplers and slotted lines are available for various standard waveguide bands between 1 GHz to above 220 GHz.
A rectangular waveguide supports TM and TE modes but not TEM waves because we cannot define a unique voltage since there is only one conductor in a rectangular waveguide.
A rectangular waveguide cannot propagate below some certain frequency. This frequency is called the cut-off frequency.
Modes of operation:
