Modeling of Cylindrical Cables Based on PEEC Method and a Surface Admittance Operator

摘要

We present a fast and efficient modeling method for cylindrical cables based on PEEC method and a surface admittance operator. The proposed method uses an admittance operator to build new basis functions, which can make the calculation of partial impedance and partial inductance faster and capture the current distribution caused by skin effect (SE) and proximity effect (PE). Simulation examples confirm the accuracy and efficiency of the method.
