Noun
Transmission.
Source: Webster's dictionaryA basic IR spectrum is essentially a graph of infrared light absorbance (or transmittance ) on the vertical axis vs. frequency or wavelength on the horizontal axis. Source: Internet
Alternatively, the entire wavelength range is measured using a Fourier transform instrument and then a transmittance or absorbance spectrum is generated using a dedicated procedure. Source: Internet
Another derivation of the formula, based on a physical reflectance transmittance model, can be found in a 1981 paper by Bruce A. Wallace. citation A third approach is found by starting out with two very simple assumptions. Source: Internet
Microwave frequency bands Rough plot of Earth's atmospheric transmittance (or opacity) to various wavelengths of electromagnetic radiation. Source: Internet
Microwaves main Plot of Earth's atmospheric transmittance (or opacity) to various wavelengths of electromagnetic radiation. Source: Internet
If a plane wave, confined to the xz plane, is incident on a dielectric with an angle and wavevector then a transmitted ray will be created with a corresponding angle of transmittance as shown in the figure above. Source: Internet
