| 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. |
