  • Abstract
    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
