Waves in accessible amplitude bear in all directions, as all-around waves. In this way they lose their ability proportionally to the aboveboard of the distance; that is, at a ambit R from the source, the ability is the antecedent ability disconnected by R2. The waveguide borders the beachcomber to advancement in one dimension, so that (under ideal conditions) the beachcomber loses no ability while propagating.
Waves are bedfast central the waveguide due to absolute absorption from the waveguide wall, so that the advancement central the waveguide can be declared about as a "zigzag" amid the walls. This description is exact for electromagnetic after-effects in a alveolate metal tube with a ellipsoidal or annular cantankerous section.
