TTEM小室芯板不同接地方式对场分布影响的分析
Analysis of the Field Distributing under the Influence of the
Different Groundings of the TTEM Cell'Septum
摘要 通过HFSS对TTEM小室的非激励板的不同接地情况下的内部场强分布进行了仿真,从分析的结果中可以发现:在低频段,非激励芯板用金属板接地和用多个金属杆接地对TTEM小室内部场强的均匀性效果相近,但是到了高频段,前者对场强的均匀性的效果要比后者更稳定。这为TTEM小室非激励板的接地处理提供了依据。

Abstract The inner electric field distributing of the TTEM cell with different groundings of
the passive septum are simulated by HFSS. From the results,we can find that at the low
frequency, the passive septum with a metal board grounding has the similar effort on
the electric field uniformity of the TTEM cell to the passive septum with more metal
poles grounding,but at the high frequency,the former has a better effort on the electric
field uniformity than the latter. This provides a base for the management of grounding
of the TTEM cell's passive septum.
Keywords TTEM;grounding;electric field uniformity
