WaveguidesΒΆ

A waveguide is a structure that guides waves by restricting the transmission of energy to one direction. Common types of waveguides include acoustic waveguides which direct sound, optical waveguides which direct light, and radio-frequency waveguides which direct electromagnetic waves other than light like radio waves.

Critical wavelength of waveguide

The critical wavelength of a waveguide is such that signals with a wavelength greater than the critical one become attenuated and do not propagate in the waveguide.
