Standing wave ratio — In telecommunications, standing wave ratio (SWR) is the ratio of the amplitude of a partial standing wave at an antinode (maximum) to the amplitude at an adjacent node (minimum), in an electrical transmission line. The SWR is usually defined as a … Wikipedia
standing wave — i. A wave in the atmosphere that remains stationary in a moving fluid. Mountain waves and lee waves are two standing waves normally encountered in flight. See mountain wave. ii. A stationary wave or wave pattern formed in a vibrating body (e.g.,… … Aviation dictionary
