wave guide
Definition
Noun: A wave guide is a hollow, tubular metal structure designed to confine and direct electromagnetic waves, particularly microwaves, along a specific path with minimal energy loss. It functions as a transmission line for high-frequency signals.
Usage
A wave guide is used to efficiently transfer microwave energy from one point to another, typically within specialized equipment like radar systems, satellite communications, or scientific apparatus. * The radar system's efficiency depends on a precisely engineered wave guide. * The technician replaced the damaged wave guide to restore the signal path.
Advanced Usage
- Dielectric Waveguide: A waveguide that uses a solid dielectric rod instead of a hollow metal tube to guide waves, often used in optical fibers.
- Waveguide Mode: Refers to a specific pattern of electromagnetic field distribution that can propagate within the waveguide.
Variants and Related Words
- Waveguide (noun): An alternative, often more common, single-word spelling for "wave guide".
- Waveguiding (noun/adj): The action or principle of confining and directing waves. (e.g., "The waveguiding properties of the material.")
Synonyms
- Microwave Guide
- Conduit (in the specific context of electromagnetic transmission)
Related Phrases
- Waveguide Bend: A section of waveguide that is curved to change the direction of the wave path.
- Waveguide Aperture: The opening or end of a waveguide from which waves are emitted or received.
Noun
-
a hollow metal conductor that provides a path to guide microwaves; used in radar
