Improved 3D full-wave multilevel Green's function interpolation method

Y. Shi, Chi Hou Chan

Abstract

A subset of infinitely smooth radial basis functions (RBFs), Bessel (BSL) RBF is proposed to improve the computational efficiency of the multilevel Green's function interpolation method for the solution of 3D complex full-wave electromagnetic problems. Numerical results reveal that the interpolation accuracy and efficiency, and computer memory storage requirement are greatly enhanced using the proposed BSL RBF when compared to previously used RBFs.
