- A waveguide is an electromagnetic feed line that guides waves, such as electromagnetic waves or sound, with minimal loss of energy by restricting the transmission of energy to one direction.
- Without the physical constraint of a waveguide, wave intensities decrease according to the inverse square law as they expand into three-dimensional space.
- Waveguides only allow frequencies above the cut-off frequency and do not pass below the cut-off frequency. Hence it acts as a high pass filter.
The frequency response of the waveguide is:
where, ωc is the cut-off frequency
