研究了双谐振超材料中的二次谐波产生。我们表明，SH产生可以增强时，满足谐振条件的SH频率以及基频。双谐振超材料的单元格由两个耦合的谐振器组成，其中一个谐振在基频，而另一个谐振在SH频率附近。我们观察到双共振超材料中的SH产生是单共振超材料中的4.6倍。
We investigate second harmonic (SH) generation in a doubly resonant metamaterial. We show that SH generation can be enhanced when the resonant condition is satisfied for the SH frequency as well as for the fundamental frequency. A unit cell of the doubly resonant metamaterial consists of two coupled resonators, one of which resonates at the fundamental frequency, whereas the other resonates around the SH frequency. We observe that the SH generation in the doubly resonant metamaterial is 4.6 times as large as that in a singly resonant metamaterial.
