摘要

高阶模的共振决定了TEM单元的可用带宽。由于共振模式及其特征场分布是已知的，因此采取了选择性抑制高阶模式共振的措施。因此，在不影响TEM模式的情况下，扩展了小区的带宽。在单元格中加载物体会导致截面几何形状的突然变化。研究了物体的大小和位置对共振的影响。

Higher order mode behavior in loaded and unloaded TEM cells

The resonances of higher order modes determine the usable bandwidth of a TEM cell. Since the resonating mode and its characteristic field distribution are known, measures are taken to selectively suppress resonances of higher order modes. Thus the bandwidth of the cell is expanded without affecting the TEM mode. Loading the cell with objects results in abrupt changes of the cross sectional geometry. The effects on the resonances due to the size and position of the objects are examined.
