Interpreting synchrotron infrared nano-spectra of hydroxyapatite through Kramers-Kronig relations and complex Lorentzian oscillators [PDF]
This study introduces a hybrid numerical-analytical methodology for interpreting, for the first time, both the amplitude and phase of Synchrotron Infrared Nanospectroscopy (SINS) spectra of hydroxyapatite (HA) thin films.

Complex Refractive Index Spectrum of CsPbBr3 Nanocrystals via the Effective Medium Approximation [PDF]
We 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 ...

Topology-Enabled Finite-Band Absorption Framework Based on a Bioinspired Nested Dual-Loop Architecture. [PDF]
A nuclear‐pore‐inspired nested dual‐loop architecture redistributes electromagnetic energy through coupled transport, confinement, and dissipation pathways. Integrated with Co/Fe3O4 dual‐magnetic composites and topology optimization, the 11‐mm‐thick absorber delivers continuous 2–40 GHz attenuation, raises finite‐band structural utilization to 82%, and

Better resolved low frequency dispersions by the apt use of Kramers-Kronig relations, differential operators and all-in-1 modelling [PDF]
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

Giant Magneto-Optical Effects in Two-Dimensional Flat-Band Antiferromagnets. [PDF]
RuOCl2${\rm RuOCl}{_2}$, a two‐dimensional antiferromagnet, hosts energy bands with pronounced directional flatness. This study demonstrates that the flat‐band‐induced optical transitions yield strongly anisotropic absorption and a record‐large magneto‐optical Schafer–Hubert effect, alongside exceptional linear dichroism exceeding 50%.

The investigation of the optical and morphological properties of metal iron oxide-based Fe2O3-WO3-ZrO2 and Fe2O3-WO3 nanocomposites [PDF]
Iron oxide nanocomposites Fe2O3-WO3 and Fe2O3-WO3-ZrO2 were effectively synthesized in this study using the solid-state reaction technique and using Tauc plot analysis of diffuse reflectance spectroscopic data in the 350–700 nm spectral range, the ...

Harnessing the Missing Spectral Correlation for Metasurface Inverse Design [PDF]
A 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.

Polarization-aware UAV deployment for reliable MIMO communication in forested environments. [PDF]
Unmanned Aerial Vehicles (UAVs) equipped with Multiple-Input Multiple-Output (MIMO) communication systems are increasingly deployed to restore or extend connectivity in forested and remote regions where terrestrial infrastructure is unavailable. However,

BIREFRINGENCE AND EXCITON SPECTRA OF CuAlSe2 AND CuAlS2 CRYSTALS [PDF]
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.
