The reflection and transmission coefficients, which govern the amplitude of each reflection, vary with angle of incidence and can be used to obtain information about ( among many other things ) the fluid content of the rock.

Tunneling through a double barrier was first solved in the Wentzel-Kramers-Brillouin ( WKB ) approximation by David Bohm in 1951, who pointed out the resonances in the transmission coefficient occur at certain incident electron energies.
33.
In a similar manner, a transmission coefficient, \ scriptstyle T, can be defined to describe the portion of the wave, \ scriptstyle V _ \ mathrm t, that it is transmitted in the forward direction:

It is interesting that while the transmission coefficient of a potential barrier is always lower than one ( and decreases with increasing barrier height and width ), two barriers in a row can be completely transparent for certain energies of the incident particle.
35.
The best combination of a smooth transfer characteristic, low distortion, wide range of adjustment, and nearly equal rates of increase and decrease of the transmission coefficient is achieved in a series-parallel circuit composed of two ROs and a series resistor.
36.
The concentration of dyes or silver halide crystals remaining on the film after development is referred to as optical density, or simply "'density "'; the optical density is proportional to the logarithm of the optical transmission coefficient of the developed film.
37.
In the early 1970s, Tsu, Esaki, and Chang computed the two terminal current-voltage ( I-V ) characteristic of a finite superlattice, and predicted that resonances could be observed not only in the transmission coefficient but also in the I-V characteristic.
38.
The transmission coefficient for FTIR is highly sensitive to the spacing between the third medium and the second medium ( the function is approximately exponential until the gap is almost closed ), so this effect has often been used to modulate optical transmission and reflection with a large dynamic range.
39.
The dual circuit of the bandstop filter can be obtained simply equating the reflection coefficient of the bandstop FSS to the transmission coefficient of the bandpass FSS to obtain ( if we use L 1, C 1 for the bandstop patch FSS and L 2, C 2 for the bandpass mesh FSS ):

A non-thermally-separated frame from an aluminium window has a thermal transmission coefficient Uf of 6.8 W / m2K . If this system is thermally separated with an insulating profile with a width of 42 mm, then the thermal transmission coefficient can be reduced to 1.3 W / m2K
