Waveguides are hollow metallic tube structures used for transmitting
electromagnetic waves by reflections from inner walls. These are most
commonly used at microwave frequencies. Waveguides are commonly used to
feed horn antennas and parabolic dishes.

Description
The waveguide object is an open-ended rectangular waveguide. The
default rectangular waveguide is the WR-90 and functions in the X-band. The
X-band has a cutoff frequency of 6.5 GHz and ranges from 8.2 GHz to 12.5 GHz.
