摘要

径向基函数插值作为多层格林函数插值方法的核心，由于光谱精度方法对均匀分布点的不适应，在边界附近存在较大的插值误差。为了解决这一问题，提出了一种边界聚类分布的插值网格模式来改进格林函数插值。该网格的应用大大提高了MLGFIM的效率。数值实验证明了该方法的准确性和有效性。

Simulating composite metallic and dielectric objects by an improved multilevel Green's function interpolation method

As the kernel of multilevel Green's function interpolation method (MLGFIM), radial basis function interpolation always has large interpolation errors near boundary because of an ill-conditioning of spectrally accurate methods on uniformly distributed points. To remedy this problem, a new interpolation grid pattern with boundary clustered distribution is proposed to improve the Green's function interpolation. By applying this new grid, the efficiency of MLGFIM is greatly enhanced. Numerical experiments have been given to demonstrate the accuracy and efficiency of the proposed method.
