Abstract
All TEmnp resonances in a TEM cell have been suppressed by cutting the cell walls longitudinally. The TEmnp resonances and propagating TEM mode were not affected. The suppressed resonances have a residual interaction with a biological body inside the cell. Because of this, the modified cell can only be used for bioeffects dosimetry studies at a small number of frequencies above the upper limit for the original cell. Where an accuracy of only + or - is required, such as in some EMC studies, the effective bandwidth of the modified cell is twice that of the original cell. The two main goals of this study are to suppress the TEmnp resonances and to evaluate the usable bandwidth of the modified TEM cell for the whole-body dosimetry work.
