T-E (TE) represents the
layer transmissivity, i.e. the fraction of radiation that is not absorbed
after travelling through a distance d inside a medium characterised by a
dielectric function E.

Transmittance-E (TE) represents the
fraction of the incident radiation that is transmitted by a sample with a plate shape.
Its expression take into account for multiple reflections (no interference
effects) and depends on the dielectric functions of the incident medium
Ei, those of the material Eo and the
thickness d of the sample.
Function signature : Transmittance-E(x,Ei,Eo,Thickness)
Units
The spectral dependance must be expressed in wave numbers (cm-1) and
the thickness in (cm).

Transmittance-N (TN) represents the
fraction of the incident radiation that is transmitted by a sample with a plate shape.
Its expression take into account for multiple reflections (no interference

Ni, those of the material No and the
thickness d of the sample.
Function signature : Transmittance-N(x,Ni,No,Thickness)

The spectral dependance must be expressed in wave numbers (cm-1) and
the thickness in (cm).

Transmittance-RT (TRT) represents the
fraction of the incident radiation that is transmitted by a sample with a plate shape.
Its expression take into account for multiple reflections (no interference
effects and depends on the reflectivity R and the layer transmissivity
