QUASI-STATIC COMPLEX IMAGE METHOD FOR A CURRENT POINT SOURCE IN HORIZONTALLY STRATIFIED MULTILAYERED EARTHBy Z. X. Li, G.-F. Li, J.-B. Fan, and Y. YinAbstract: Based on quasi-static electromagnetic field theory, recently grounding system under alternative currents (AC) substation has been studied with equal potential and unequal potential models. In these numerical models, the closed form of Green's function for a point source within a horizontal multilayered earth model and its quasi-static complex image method have been fully discussed. However, less information about how to achieve the closed form of Green's function through Matrix Pencil method is presented in these references. In this paper, we discuss how the kernel of the Green's function can be expanded into a finite exponential series.
