Temperature dependences of the optical path difference, variable part of the refractive index and thickness of triglycine sulphate crystal for three crystallophysic directions are studied in the temperature range of 39–70 ...

A method has been elaborated to reconstruct the material absorption spectrum k(ω') in the ranges of fundamental excitations (ω') basing on the refractive index dispersion n(ω) in the material transparency range (ω). The ...

Based on solving the Kramers-Kronig integral equation, binding the spectrum of refractive index n(ω) of dielectric experimentally measured in the range of transparency (ω) and its spectrum of absorption index k(ω′) in ...
