Self-action of light in a nonlinear metamaterial composed of metal helices

We used the high-order finite element method to numerically study the self-action of light in a nonliner metamaterial composed of gold helices. It is shown that such a metamaterial can selectively reflect the waves with certain circular polarization. The impact of the nonlinear optical response of g...

Zusammenfassung:We used the high-order finite element method to numerically study the self-action of light in a nonliner metamaterial composed of gold helices. It is shown that such a metamaterial can selectively reflect the waves with certain circular polarization. The impact of the nonlinear optical response of gold on the value of the transmission coefficient and the frequency range, in which this selective reflection occurs, is studied.
