Abstract
Investigation of electrical fast transients and their influence on signal integrity in shielded cables is an important topic in the field of electromagnetic compatibility (EMC). Signal integrity problems can occur on the basis of coupled disturbances on the transmitting cable in form of fast transients caused by some electromagnetic interference (EMI) current in the shield together with the transfer impedance. The aim of this paper is to develop an applicable model to calculate and estimate the behavior of cable shields and their transfer impedance over a wide frequency spectrum and under the direct influence of fast transient phenomena.
