研究了飞秒光脉冲与二维分布的金属圆柱腔体的散射引起的线性和非线性效应。特别是，通过采用基于多重散射矩阵算法的数值方法，我们证明，在基频和二次谐波，这样的阵列的金属纳米线支持本地化（腔）表面等离子体极化激元模式的特征寿命范围从几十飞秒到一百多飞秒。
We investigate linear and nonlinear effects induced by the scattering of femtosecond optical pulses by cavity-shaped two-dimensional distributions of metallic cylinders. In particular, by employing a numerical method based on the multiple scattering matrix algorithm, we demonstrate that, at both the fundamental frequency and the second harmonic, such arrays of metallic nanowires support localized (cavity) surface plasmon–polariton modes with characteristic lifetime ranging from a few tens of femtoseconds to more than a hundred of femtoseconds.
