    "abstract": "We study the second-harmonic generation in left-handed metamaterials with a\nquadratic nonlinear response. We demonstrate a novel type of the exact phase\nmatching between the backward propagating wave of the fundamental frequency and\nthe forward propagating wave of the second harmonics. We show that this novel\nparametric process can convert a surface of the left-handed metamaterial into\nan effective mirror totally reflecting the second harmonics generated by an\nincident wave. We derive and analyze theoretically the coupled-mode equations\nfor a semi-infinite nonlinear metamaterial. We also study numerically the\nsecond-harmonic generation by a metamaterial slab of a finite thickness, and\nreveal the existence of multistable nonlinear effects.",
