reflection coefficient

[ri′flek·shən ‚kō·i‚fish·ənt]
(physics)
The ratio of the amplitude of a wave reflected from a surface to the amplitude of the incident wave. Also known as coefficient of reflection.

Reflection Coefficient

 

the ratio of the radiant flux reflected by a body to the radiant flux incident on it. The concept of an amplitude reflection coefficient, that is, the ratio of the amplitudes of the reflected and incident waves, is sometimes used —for example, for radio waves. In general, the reflection coefficient is the sum of a direct reflection coefficient and a diffuse reflection coefficient.
