Abstract

The Partial Element Equivalent Circuit (PEEC) method is widely used to model a large variety of electrical systems ranging from interconnects to antennas and packaging. A key aspect in the development of the method is the computation of interaction integrals, namely partial inductances and coefficients of potential. In this work, a novel semi-analytical approach to the computation of the self-interaction integral over rectangular domains is proposed for the zero thickness case as it occurs in the case of the coefficients of potential and partial inductances of very thin conductors and in the surface integral equation based formulation. The proposed semi-analytical formula is verified by comparison with more standard integration schemes.

矩形上全波自相互作用积分的半解析形式
部分元件等效电路(PEEC)方法被广泛用于模拟各种各样的电气系统,从互连到天线和封装。该方法发展的一个关键方面是相互作用积分的计算,即部分电感和电位系数。在这项工作中,提出了一种新的半解析方法来计算矩形域上的自相互作用积分,因为它发生在极薄导体的电位和部分电感系数以及基于表面积分方程的公式中的零厚度情况下。通过与更多标准积分方案的比较,验证了所提半解析公式的正确性。
