Waveguide - Wikipedia
网页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.
Waveguide (radio frequency) - Wikipedia
网页Waveguides are almost exclusively made of metal and mostly rigid structures. There are certain types of "corrugated" waveguides that have the ability to flex and bend but only used where essential since they degrade propagation properties.
What are Waveguides? Definition, Types, Modes, Parameters, …
网页Definition: Waveguides are a special category of transmission line that is used to guide (direct) the waves (radiation) along the length of the tube. These are typically a hollow metallic tube that acts as the medium to transfer or transmit power.
Waveguide (optics) - Wikipedia
网页An optical waveguide is a physical structure that guides electromagnetic waves in the optical spectrum. Common types of optical waveguides include optical fiber waveguides, transparent dielectric waveguides made of plastic and …
