摘要:
针对电气产品中的屏蔽问题,使用时域有限积分算法,对电气电子产品的机箱外壳开孔问题作了电磁场仿真,适用于辐射电磁干扰典型的频段30 MHz～1 GHz,计算并比较其屏蔽效能.仿真计算的结果表明,在相同面积、不同形状的开孔情况下,电场屏蔽效能和磁场屏蔽效能的特性,为设计电磁兼容屏蔽提供了帮助.
Abstract:
Apertures in a enclosure of electronic equipment are main channels of radio disturbance radiated.Based on FIT,this paper simulates electromagnetic field for Shielding Efficiency,applied on typical radiated emission frequency(30 MHz～1 GHz),their shilding efficiencies are computed and compared.The simulation results show that SE for E-field and H-Field are different under the same area and different shapes.It is helpful for engineers who are designing EMC shields.
