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:
“Wind goes from farm to farm in wave on wave,
But carries no cry of what is hoped to be.
There may be little or much beyond the grave,
But the strong are saying nothing until they see.”
—Robert Frost (1874–1963)
“John Eliot came to preach to the Podunks in 1657, translated the Bible into their language, but made little progress in aboriginal soul-saving. The Indians answered his pleas with: ‘No, you have taken away our lands, and now you wish to make us a race of slaves.’”
