Wavenumber

A simple Cocoa application that converts between energy (eV), wavenumber (1/cm) and wavelength (um). In addition the application calculates the bandgap of common III-V semiconductors for a user defined temperature.

This is an approximation of the Voigt function within the Humlicek regions 3 and 4. The approximation is one given by S.M. Abrarov et. al. "High-accurace approximation of the complex probability function byFourier expansion of exponential multiplier" (2010).x = sqrt(ln(2))*(nu - nu0)/alphaDy =...

This set of functions simply provides an easy way to work with the dispersion relation of surface waves, given by omega(k) = sqrt ( tanh(k*h0) * (g*k + gamma*k^3/rho))where omega is the pulsation (in rad/s), k the wavenumber (in 1/m), h0 the depth, g the gravity, gamma the surface tension and rho...

The Ejs Wave Packet model displays the motion of an approximate wave packet. The simulation allows an arbitrarily wave packet to be created. The default dispersion relation, with the frequency equal to the wavenumber, results in a wavepacket that does not spread. The amplitude, maximum and...
