吉赫橫電磁波傳輸室傳輸特性的寬頻帶分析

WIDE BAND ANALYSIS OF TRANSMISION CHARACTERISTICS IN GTEM CELL

  • 摘要: 吉赫橫電磁波傳輸室(GTEMcell)上限工作頻率可達(dá)幾個(gè)吉赫，因而在電磁兼容測量中得到越來越廣泛的重視和應(yīng)用。本文在非正交坐標(biāo)系下采用FDTD(時(shí)域有限差分)法求解電磁波在GTEMcell中的傳輸特性，給出了GTEMcell中TEM模的橫向分布和縱向分布，分析了高階模對場分布均勻性的影響，由此確定了GTEMcell的上限工作頻率范圍。計(jì)算及分析結(jié)果對GTEMcell的設(shè)計(jì)和使用具有重要意義。
    Abstract: The TEM cell is limited in the upper useful test frequency but GHz TEM (GTEM) cell permits to overcome this restriction. This paper analyzes the transmisssion characteristics in GTEM cell using FDTD method in the nonorthogonal coordinate. The field distributions have been calculated and the upper useful frequency has been analyzed. The results are of great value to the using and designing of GTEM cells.
