Electromagnetically induced transparency (EIT) is a coherent optical nonlinearity which renders a medium transparent within a narrow spectral range around an absorption line. Extreme dispersion is also created within this transparency "window" which leads to " slow light ", described below.
Rayleigh–Gans approximation has been applied on the calculation of the optical cross sections of fractal aggregates. [6] The theory was also applied to anisotropic spheres for nanostructured polycrystalline alumina and turbidity calculations on biological structures such as lipid vesicles [7] and bacteria. [8]

It is not possible to describe the interaction of an optical electromagnetic wave with a metal using classical optical theory. Nonetheless, some of the main features can be described, at least in quantitative terms, provided the frequency dependence of conductivity and the role of free and bound electrons are taken into account.
Forecasts for a near-term stock-market correction are getting more plentiful. The S&P 500's recent performance and technical indicators suggest a possible downturn.
He also continued work on several topics in high-energy collision theory, including the analysis of hadron collisions, and the statistical correlation of particles produced in high-energy reactions. [11] [12] [13] Roy Glauber’s early work on multiple scattering theory, started in the 1950s and was continued with his students such as Victor ...
