Abstract

In order to predict the time domain response of the shielded twisted-pairs coupling from external transient electromagnetic field, an FDTD-MTL hybrid numerical model is developed. The coupling model is divided into two systems: external system and internal system solved by the FDTD method and the MTL theory respectively. These two systems are linked by transfer impedance and transfer admittance of shielded cables. The accordance of model predictions and experimental results indicates that the FDTD-MTL hybrid method is valid.
