NLS-Simulate

NLS-Simulate was made to interactively predict second harmonic and sum frequency scattering patterns using the Rayleigh-Gans-Debye approximation. The controls on the left side determine simulation parameters. A detailed description of all controls is given below. Shown are the nonlinear light scattering intensities for the four allowed polarization combinations ppp, ssp, sps and pss. All intensities have been divided by R4.

This program is an updated version of NLS-Simulate, which can calculate SFS patterns from ellipsoidal particles.
