Second harmonic generation of magnetic and dielectric multilayers.

The second harmonic generation of antiferromagnetic and dielectric multilayers is analysed by using a conventional nonlinear optics approach and transfer matrix formalism. The theoretical modelling of the multilayers is configured in Voigt geometry in order to observe second harmonic transmission and reflection through the film system, with the assumption of weak nonlinearity and no depletion of incident waves. With these, some of the linear and second harmonic transmissions and reflections are calculated numerically and shown graphically.
