A method for determining the weak electromagnetic coupling path

The present invention discloses a method for determining the weak coupling an electromagnetic path, belonging to technical field of electromagnetic compatibility. The method works by the apparatus of FIG electromagnetic interference coupling into the network, and then converted to the coupling network has coupled thereto for coupling to simplify the drawing and to FIG. Finally, the shortest path algorithm to find out the tracking electromagnetic coupling network weak link coupling path, to solve the electromagnetic compatibility of electronic systems troubleshooting is not targeted, time-consuming problem. Consider electromagnetic interference coupling network, there are primary or secondary coupling path, shortest path tracing the path of looking weak coupling of electromagnetic interference, the main coupling process accurate understanding of interfering signals, the electromagnetic compatibility rectification work more focused and effectiveness.
