fitting.lorOscIm

fitting.lorOscIm(w, A, w0, dw)

Imaginary part of a Lorentz oscillator model for the dielectric function.

Parameters:
  • w (array) – Angular frequency.
  • A (float) – Amplitude.
  • w0 (float) – Resonance frequency.
  • dw (float) – Damping rate.
Returns:

f(w) = \frac{A \Delta \omega \omega}{ (\omega_0^2 - \omega^2)^2 + \Delta \omega^2 \omega^2 }.
