Abstract: Electromagnetic interference mechanism of interconnect cables was analyzed, and mathematical model of multi-conductor interconnect crosstalk coupling was established. Capacitance matrix and inductance matrix of mine-used four-core interconnect cables were extracted using the finite element analysis software Ansys. The electromagnetic interference of interconnect cables of electronic equipment was predicted and analyzed applying field-road combined method, and the numerical calculation result was consistent with the theoretical analysis result.
