Error Estimator for Cauer Ladder Network Representation

The Cauer ladder network (CLN) method enables to construct a reduced-based circuit model of analytical or numerical models, e.g., finite-element (FE) model, under quasistatic approximation. This article proposes an estimator that provides guaranteed upper bounds of the truncation error due to the CLN method. The error estimator is tested on an analytical model and an FE model to validate the approach.
