摘要
GTEM是几年前才发明的EMC/EMI测量装备,具有很大的重要性。文章重点论述以下几个问题:(1)传统的横电磁传输室(TTC)的缺点;(2)GTEM的原理及可能达到的技术指标;(3)特性阻抗的无穷级数公式;(4)对特性阻抗进行编程计算的方法,以及计算实例。最后,讨论了准静态分析所存在的问题,从而明确了进一步研究的方向。
The new GTEM cell is a important equipment in EMC/EMT measurements, which just has invented by a few years. In this paper, we discusses the fol- lowing problems: (1) Disadvantages of the traditional TEM transmission cell; (2) Principle and specification of the GTEM cell; (3) Infinite series equations of characteristic impedance of the GTEM cell; (4) Method of programing computation and computing results. Finally, we note the confine of the quasi-static analysis scheme, and so the research di- rection is becoming clear.
