提出了一种具有V形开口的三维纳米银圆管阵列结构,这种结构可被应用于折射率传感器中。利用时域有限差分法对V形开口纳米银圆管阵列的透射特性进行研究。结果表明:当入射光的电场偏振方向垂直于开口的方向时,在可见光和近红外波段的透射光谱上存在3个共振透射峰,分别对应着一个传导型表面等离子体共振(PSPR)模式和两个不同机理的局域表面等离子体共振(LSPR)模式。讨论了阵列周期、圆管直径、圆管高度和圆管顶部缝隙大小等参数对透射峰的波长以及半峰全宽(FWHM)的影响。通过调谐结构参数,优化V形开口纳米银圆管阵列的LSPR传感性能,得到最大高达13.2的品质因子。

The goal of this paper is to achieve a computational model and corresponding efficient algorithm for obtaining a sparse representation of the fitting surface to the given scattered data. The basic idea of the model is to utilize the principal shift invariant(PSI) space and the l_1 norm minimization. In order to obtain different sparsity of the approximation solution, the problem is represented as a multilevel LASSO(MLASSO)model with different regularization parameters. The MLASSO model can be solved efficiently by the alternating direction method of multipliers. Numerical experiments indicate that compared to the AGLASSO model and the basic MBA algorithm, the MLASSO model can provide an acceptable compromise between the minimization of the data mismatch term and the sparsity of the solution. Moreover, the solution by the MLASSO model can reflect the regions of the underlying surface where high gradients occur.
