Abstract
Experimental investigations reveal significant nonlinear responses from metallodielectric stacks (MDSs) with constituent metal films of silver (Ag), gold (Au) or copper (Cu). In particular, the Cu dielectric MDS exhibited large non-linear absorption. Nevertheless, there is a need to investigate these materials with more faithful numerical techniques in order to account for the underlying physical processes observed in the experiments. We apply a Finite Element Method (FEM) with radial symmetry to numerically solve for the Z-scan experiment of a MDS using the corresponding nonlinear Maxwell equations. The amplitude and the phase of the electromagnetic field at the exit interface of the MDS are used for transforming to the far-field regime.
