Complex Refractive Index Spectrum of CsPbBr3 Nanocrystals via the Effective Medium Approximation [PDF]
NanomaterialsWe have estimated the intrinsic complex refractive index spectrum of a CsPbBr3 nanocrystal. With various dilute solutions of CsPbBr3 nanocrystals dissolved in toluene, effective refractive indices were measured at two different wavelengths using ...

Better resolved low frequency dispersions by the apt use of Kramers-Kronig relations, differential operators and all-in-1 modelling [PDF]
Frontiers in Chemistry, 2016 The dielectric spectra of colloidal systems often contain a typical low frequency dispersion, which usually remains unnoticed, because of the presence of strong conduction losses. The KK relations offer a means for converting into data. This allows

Harnessing the Missing Spectral Correlation for Metasurface Inverse Design [PDF]
Advanced ScienceA long‐held tenet in computer science asserts that the training of deep learning is analogous to an alchemical furnace, and its “black box” signature brings forth inexplicability.

BIREFRINGENCE AND EXCITON SPECTRA OF CuAlSe2 AND CuAlS2 CRYSTALS [PDF]
Journal of Engineering Science (Chişinău), 2020 The excitonic reflection spectra of CuAlS2 and CuAlSe2 crystals were measured at the temperature of 10 K for polarizations E||c and E⊥c. Ground and excited states of the excitons were found out in the investigated spectra.

Using The Kramers-Kronig Transforms To Retrieve The Conductivity From The Effective Complex Permittivity [PDF]
Advances in Radio Science, 2018 While measuring the effective permittivity of dispersive material it may be of interest to distinguish between conductivity losses (caused by free electrons) and dielectric losses (caused by bounded electrons) which both are included in the imaginary ...
