reflection coefficient
Technical term in physics and engineering, especially in optics, electromagnetics, and transmission line theory. Describes the ratio of reflected wave amplitude to incident wave amplitude.
The reflection coefficient of this antenna is kept below 0.2.
When the reflection coefficient is large, signal reflection becomes strong.
Transmission coefficient; measures the ratio of transmitted wave amplitude to incident wave amplitude, complementing the reflection coefficient.
Reflectance; often used for power or intensity ratio, while 反射係数 can refer to amplitude ratio and may be complex-valued.

ambient reflection coefficient
Compound of 反射 (reflection) and 係数 (coefficient). A straightforward technical term with no special historical derivation.
