| reflection coefficient |
(fiber optic) The fraction of light power reflected backward at the fiber end face. This accounts for about a .2 to .3 dB loss, typically.

| reflection |
1. a turning or bending back; a bending back upon its course. 2. in physics, the turning back of a ray of light, sound, or heat when it strikes against a surface that it does not penetrate. The ray before reflection is known as the incident ray; after reflection, it is the reflected ray. 3. an image produced by this process. 4. a special form of reentry in which an impulse crosses a narrow area of diminished responsiveness to excite distal tissue, pauses long enough for repolarization of proximal tissue, and returns, retracing its pathway and reexciting the same fibers in reverse rather than traversing a circuit. If the returning impulse is strong enough, a seesaw movement of current can result, causing tachyarrhythmias.

| reflection coefficient |
The ratio of the voltages corresponding to the reflected and incident waves at the antenna's input terminal (normalized to some impedance Z0). The return loss is related to the input impedance Zin and the characteristic impedance Z0 of the connecting feed line by: Gin = (Zin - Z0) / (Zin+Z0).
