Abstract :
Field strength distributions and perturbations have been investigated in a GTEM cell 1750, which is about 8m long. One of the critical frequencies at 123 MHz has been used to expand the GTEM field structure analysis. At this frequency a rectangular cross section (w=3.20 m; h=1.60 m) is measured with a field sensor, giving E, H fields and phase. In parallel a computer simulation using time domain finite difference code was performed. The results compare favorably well. This means for the first time a numerical model of the GTEM cell is now available and validated
