Complex refractive index. The Kramers–Kronig relations are used to relate the real and imaginary portions for the complex refractive index of a medium, where is the extinction coefficient. [12] Hence, in effect, this also applies for the complex relative permittivity and electric susceptibility.
The Kramers–Kronig relations allow one to calculate the refractive index profile and thus also the chromatic dispersion of an optical material solely from its frequency-dependent absorption losses, which can be measured over a large spectral range.
5 de abr. de 2022 · In this work, we introduce a way to perform a Kramers-Kronig analysis of such reflectance spectra without the need to extrapolate the measured data for higher wavenumbers beyond the measurement range. Furthermore, we introduce and compare very simple and reliable material-independent ways to extrapolate the measured data for lower ...
Abstract. The Kramers–Kronig relations establish a fundamental relationship between the dispersions of the real and imaginary parts of the susceptibility or the dielectric function. This way refraction of light and energy dissipation appear to be interconnected phenomena.
26 de feb. de 2020 · By using bright commodity dyes that fulfil this absorption requirement, we demonstrate the use of the Kramers–Kronig relation to predictively obtain refractive index values in water solutions that are otherwise only attained with toxic specialised liquids.
Check the Kramers-Kronig consistency of the real and imaginary parts of the dielectric functions given by Debye’s model, the Drude formula, and the oscillator model.
