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:
“Through the dark cold and the empty desolation,
The wave cry, the wind cry, the vast waters
Of the petrel and the porpoise. In my end is my beginning.”

“Lost at night in an immense forest, I only have a small light to guide me. A man appears who tells me: “My friend, blow out your candle in order to find your way.” This man is a theologian.
The sea, fluid garden filled with animals and plants.”
