摘要

本文介绍了用多层格林函数插值法(MLGFIM)对波浪操纵的超表面设计进行分析。MLGFIM允许快速矩阵向量乘法在迭代解决大规模问题。由于典型超表面的平面特性，使用快速傅里叶变换技术(FFT)可以进一步加快这种乘法。利用为MLGFIM量身定制的稀疏近似逆(SAI)预条件增强了迭代解的收敛性。

Analysis and design of metasurfaces for wave manipulation using the multilevel green's function interpolation method

This paper presents the use of multilevel Green's function interpolation method (MLGFIM) for the analysis of design of metasurfaces for wave manipulation. MLGFIM allows fast matrix-vector multiplication in an iterative solution to large-scale problems. Due to the planar nature of typical metasurfaces, this multiplication can be further speed up by using fast Fourier transform technique (FFT). The convergence of the iterative solution is enhanced using the sparse approximate inverse (SAI) preconditioner tailored for MLGFIM.
