摘要
提出了一种预测汽车电子部件电磁辐射发射的快速混合计算方法,该方法采用基于格林函数和传输线理论的解析法和多偶极子法来计算线束的电磁辐射水平,并用物理光学与等效电偶极子法对有限导电桌面进行建模。1 m观测点和远场辐射的仿真结果表明,这种快速混合计算方法与3D全波法所得结果一致,且耗时更短。
This paper proposes a fast hybrid method to calculate radiated emission from lransmission line (TL) in lesl configuration aecording Io CISPR 25. The hybrid method employs an analylic method or a multiple-dipole method based on Green fimelion and TL theory to calculate radiated emission from TL, and then combines physical oplies (PO) and equivalenl electric dipole method (EEDM) to approximately compute radiated emission from finite ground plate (FGP). Compare to 3D fill wave method this hybrid method has acceptable precision but reduces considerable computational efforts.
