Abstract

Since the interconnection cable between devices is usually much longer than those inside an enclosure, it provides a main gateway for radiated interference. An analytical method for calculating the radiated field of penetrating cable including connectors is proposed based on the cascaded network. This method takes into account the effect of connectors on signal transmission in the calculation model. The discontinuous penetrating cable is regarded as two-port cascaded model which includes three parts: internal cables inside enclosure, connectors and an external cable. The terminal voltage and current of the cable are determined according to terminal conditions, and the current distribution is solved by the transmission line theory. Finally, the electromagnetic radiation of discontinuous penetrating cable is obtained by dipole approximation method. The proposed method is verified by numerical simulation.
