采用有限元法推导了Cauer梯形网络（CLN）方法的矩阵公式，阐明了CLN方法的数学意义。CLN方法直接产生正交展开的电场和磁场，确保等效的考尔网络的涡流场。CLN方法与通过Lanczos（PVL）过程的Padé近似一样精确，但比PVL更有效地提供电路参数和正交展开。
A matrix formulation of the Cauer ladder network (CLN) method is derived using the finite-element method to clarify the mathematical aspects of the CLN method. The CLN method directly yields orthogonal expansions of electric and magnetic fields that ensure the equivalence of the Cauer network to the eddy-current field. The CLN method is as exact as the Padé approximation via the Lanczos (PVL) process but more efficiently provides the circuit parameters and the orthogonal expansion than the PVL.
