我们观察到等离子体-超材料复合材料中二次谐波的产生增强，其强度比具有相似电子密度水平的等离子体中的二次谐波强得多。我们澄清，这种特定的强烈二次谐波的产生是基于具有密度梯度的等离子体和超材料之间使用等效电路模型的电连接的额外非线性而产生的。
We observed enhanced second-harmonic-wave generation in a plasma-metamaterial composite, the intensity of which was much stronger than that in plasma with a similar level of electron density. We clarified that this specific intense second-harmonic-wave generation was derived from additional nonlinearity based on the electric connection between a plasma with a density gradient and metamaterials using an equivalent circuit model.
