Simulation Research on Shielding Effectiveness of a Material to Pulse Wave Using Nested Reverberation Chamber
摘要/Abstract
用电磁仿真软件FEKO构建一个嵌套混响室模型,在大混响室模型内再建一个小混响室模型,在小混响室壳体壁上装载屏蔽材料.首先,在无小混响室的条件下,对大混响室内某点电场的时域波形进行仿真,然后,加上小混响室,并让该点位于小混响室内,重新对该点的时域波形进行仿真.搅拌器步进转动,在搅拌器每个步进位置下重复仿真.对仿真的结果进行统计分析,得出双混响室条件下材料对脉冲波的屏蔽效能.
A nested reverberation chamber model is established with the electromagnetic simulation software FEKO.A smaller reverberation chamber model is set up in a big one.The shielding material is loaded in the shell of the small reverberation chamber.At first,in the condition without the small reverberation chamber,the time domain waveform of electric field at a point in the big reverberation chamber is simulated.Then a small reverberation chamber is added in the big one,and the point must be located in the small reverberation chamber.The time domain waveform of electric field at the point is simulated again.The stirrers are rotated step-by-step.The simulation is repeated at every rotation position of the stirrers.The simulation results are analyzed statistically.The shielding effectiveness of the material to pulse wave in the condition of nested reverberation chamber is gained.
