Small-particle composites. I. Linear optical properties.
Absorption and extinction spectra of fractal and nonfractal small-particle composites are studied. General solutions of the coupled-dipole equations with the exact operator for the dipole interaction ~including the near-, intermediate-, and far-zone terms! are found and compared with those in the quasistatic approximation. Broadscale numerical simulations of optical spectra for clusters contain...
متن کاملSmall-particle composites. II. Nonlinear optical properties.
Strong fluctuations of local fields may result in very large optical nonlinearities in small-particle composites. Enhancement associated with particle clustering is found for a number of optical processes, including fourwave mixing ~FWM!, third-harmonic generation ~THG!, Raman scattering, and nonlinear refraction and absorption in Kerr media. Field fluctuations and optical nonlinear susceptibil...
متن کاملOptical properties of normal and cancerous human skin in the visible and near-infrared spectral range.
Differences in absorption and/or scattering of cancerous and normal skin have the potential to provide a basis for noninvasive cancer detection. In this study, we have determined and compared the in vitro optical properties of human epidermis, dermis, and subcutaneous fat with those of nonmelanoma skin cancers in the spectral range from 370 to 1600 nm. Fresh specimens of normal and cancerous hu...
متن کاملestimating soil organic carbon using hyperspectral data in visible, near-infrared and shortwave-infrared (vis-nir-swir) range
background and objectives: soil organic carbon is a main soil property and particularly important for development and sustainable management of agricultural systems. soil organic matter content, which is typically measured in the form of soil organic carbon soc content, is commonly regarded as a key indicator of soil quality and utilization (liu et al., 2015). the presence of som has been prove...
متن کاملStructural and Visible-Near Infrared Optical Properties of Cr-Doped TiO2 for Colored Cool Pigments
Chromium-doped TiO2 pigments were synthesized via a solid-state reaction method and studied with X-ray diffraction, SEM, XPS, and UV-VIS-NIR reflectance spectroscopy. The incorporation of Cr3+ accelerates the transition from the anatase phase to the rutile phase and compresses the crystal lattice. Moreover, the particle morphology, energy gap, and reflectance spectrum of Cr-doped TiO2 pigments ...
