Chan] We theoretically show that it is feasible to utilize harmonic resonance modes of surface plasmon polaritons on a magnetic meta-surface for light amplification with low-gain material. The required threshold and optimal gain strength for active layer can be substantially reduced to about one-tenth as compared with those utilizing fundamental resonance modes. The findings provide a simple and practical metamaterial approach for light amplification with most of the existing active media.
