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:
““Speaking of contraries, see how the brook
In that white wave runs counter to itself.
It is from that in water we were from
Long, long before we were from any creature.”
—Robert Frost (1874–1963)
“The children [on TV] are too well behaved and are reasonable beyond their years. All the children pop in with exceptional insights. On many of the shows the children’s insights are apt to be unexpectedly philosophical. The lesson seems to be, “Listen to little children carefully and you will learn great truths.””
—G. Weinberg. originally quoted in “What Is Television’s World of the Single Parent Doing to Your Family?” TV Guide (August 1970)
