【摘要】 为便于加工,以往的GTEM cell过渡接头中斧形过渡块均采用近似设计,即侧边取直线。这样做的结果是传输损耗曲线在过渡段的分布不理想。基于修正的目的,该文给出了精确的斧形块侧边之连续曲线方程。测试结果表明:优化后的过渡接头内导体性能优于近似形状的过渡接头内导体。该设计算法对GTEM cell的研制具有重要的指导性意义。更多还原

【Abstract】 To be convenient for machining,the old axe-shaped piece in GTEM cell was approximately designed. But by theoretical calculation and TDR measurements,it is proved that the traditional transition in a GTEM cell cannot give a satisfactory characteristic impedance distribution.That means its characteristic impedance distribution is much different from the nominal 50Ωand the matching for the whole body is bad,which will deteriorate the establishment of fine traveling wave state in the GTEM cell.So this paper gives exact continuous curve equation of the transitional inner conductor’s two sides.Testing result indicates that the performance of the optimized inner conductor is better,so this arithmetic has an important meaning for directing the development of GTEM cell.更多还原
