transmittance

[tranz′mid·əns]
(analytical chemistry)
During absorption spectroscopy, the amount of radiant energy transmitted by the solution under analysis.
(electromagnetism)
The radiant power transmitted by a body divided by the total radiant power incident upon the body. Also known as transmission.

Transmittance

The ratio of the total radiant or luminous flux transmitted by a transparent object to the incident flux, usually given for normal incidence.

transmittance

When radiant flux is incident on a medium, the ratio of the flux which emerges from the medium to the flux which is incident upon it.

It is obvious that the antenna has magnificent light transmittance. We have measured the light transmittance of the antenna, which is about 80% in the area of the patch and 84% around the patch.
A rough transmittance can be estimated if the above equation is substituted into (4):
From the curves shown in the figure, it can be found that the transmittance values at wavelength of 1000 nm for the ZAZ are lower than those for IAI counterparts with the same thickness of Ag layer.
It was studied the variation of transmittance, sheet resistance and material occupancy area as a function of the angular frequency.
