The EMC analysis and design of the PCB

In this paper, the electromagnetic compatibility (EMC) of the printed circuit board (PCB) is discussed and the system design method of EMC is put forward. First, the electromagnetic interference (EMI) of the PCB is analyzed and the design process of EMC is raised. Then, we use the Ansoft Designer based on method of moments (MoM) to simulate the PCB and obtain the near field plots. According to the plots, we can optimize the layout design and improve the EMC. Simulation results are provided to show the effectiveness of the presented design method.
