transmission coefficient

[tranz′mish·ən ‚kō·i‚fish·ənt]
(physics)
The value of some quantity associated with the resultant field produced by incident and reflected waves at a given point in a transmission medium divided by the corresponding quantity in the incident wave.
The ratio of transmitted to incident energy flux or flux of some other quantity at a discontinuity in a transmission medium; for sound waves, it is called the sound transmission coefficient.
The ratio of the transmitted flux of some quantity to the incident flux for a substance of unit thickness.
(quantum mechanics)

thermal transmittance, U-value

The time rate of heat flow per unit area under steady conditions from the fluid on the warm side of a barrier to the fluid on the cold side, per unit temperature difference between the two fluids.
