Wave Guide
A waveguide is a hollow metallic conductor with a circular or square cross-section. The RF signal travels along the inside of the tube, guided by its size and shape, similar to the way sound travels in a tube. The metallic construction of the wave guide keeps it from radiating energy outwards and also prevents unwanted energy from entering the waveguide.
A waveguide is considered an unbalanced transmission line.

Famous quotes containing the words wave and/or guide:
“As the bird trims her to the gale,
I trim myself to the storm of time,
I man the rudder, reef the sail,
Obey the voice at eve obeyed in prime:
“Lowly faithful, banish fear,
Right onward drive unharmed;
The port, well worth the cruise, is near,
And every wave is charmed.””
—Ralph Waldo Emerson (1803–1882)
“New York has her wilderness within her own borders; and though the sailors of Europe are familiar with the soundings of her Hudson, and Fulton long since invented the steamboat on its waters, an Indian is still necessary to guide her scientific men to its headwaters in the Adirondack country.”
—Henry David Thoreau (1817–1862)
