Abstract： The electromagnetic compatibility and electromagnetic interference problems of many complex systems are related to cable bundles. The harness will be affected by the energy coupling of other unshielded cables or non-ideal shielded cables. The key to correct analysis is to establish a reliable analysis model. In this paper， the mixed simulation method of moment method and transmission line method of feko software is used to analyze the crosstalk characteristics between cables in several common cases.
