Refractive

Given wavelength, temperature, pressure, humidity and CO2 concentration, uses algorithms described in http://emtoolbox.nist.gov/Main/Main.asp to compute the real part of the refractive index of air. Valid for visible wavelengths and most surface-level conditions. Useful for determining the effect... Platforms: Matlab

A function for launching a bundle of rays from a fixed point in a propagation region with a specified refractive index. Documentation with examples are provided to illustrate radion beam propagation and propagation in the Earth's atmosphere. Platforms: Matlab

I designed this function with the clear intention in mind of constructing a (useful) database of refractive index. This is basically a function to organize things and (hopefully) set an standard.The function computes the refractive index using a standard form of the Sellmeier formula (as the ones...

MacFDTD is (for all I know) the only silicon layout and simulation program available for the Macintosh OS X platform. At the moment, it is incomplete and in somewhere in the alpha-beta stage of development, but I would like to get some feedback, so its been posted as it is. Disclaimer: This is... Platforms: Mac

cstodconverter is a specially designed utility that uses particle scattering data to convert a particle's scattering cross section to a diameter. This is usually non-trivial because scattering cross section is a nonlinear and non-monotonic function of diameter. The software is targetted at... Platforms: Windows

This code computes the complex dielectric constant (i.e. relative permittivity) and the refractive index of various metals using either the Lorentz-Drude (LD) or the Drude model (D) as a function of input light wavelength.Additionally, it may compute the dielectric constant of pure water using a...
