transmittance 

A measure of transmission expressed as the ratio of the intensity of the transmitted light I′ to the intensity of the incident light I, for a specified wavelength, i.e. T = I′/I. It is usually given as a percentage, i.e. T = I′/I ✕ 100. Syn. total transmittance. See absorbance; optical density.

It was studied the variation of transmittance, sheet resistance and material occupancy area as a function of the angular frequency.
As we have explained, more transmittance implies lower electrical conductivity (or higher sheet resistance) and vice versa, so the goal is to get the best initial fabrication conditions which allows us find a good equilibrium point between the properties.
where I is image intensity, J is actual scene intensity, A is atmosphere light intensity, x is the pixel of digital image, and t is transmittance describing the proportion of the light that is reflected from an object and transmitted directly to camera without scattering.
Based on DCP, the transmittance of each pixel can be calculated.
Four transmittance values for roller shades: 1%, 3%, 5% and 7% (shade absorptance 20%).
Basic results are presented as comparative graphs in the sections below, showing the impact of location, WWR, glass transmittance, shading transmittance and orientation.
Spectral reflectance and transmittance of light in snow and ice
Manual measurements of spectral irradiance above and below ice with Ramses ACC-VIS provided spectral transmittance (Fig.
Calculations for the transmittances and back reflectances corresponded within 0.
With knowledge of the internal reflectance, the transmittance and reflectance of a free standing film are then simulated with film thickness and extinction coefficient.
The basis of calculation and reporting of thermal transmittances is established by three categories of thermal anomalies as summarized below and presented in Figure 1.
