Abstract :
A methodology to generate a time-varying adjustable wave impedances inside a TEM cell is introduced for electromagnetic susceptibility tests of small electronic modules. The TEM cell is excited by two amplified arbitrary waveforms. By varying the excitation waveforms and their timing, the momentary wave impedance and field strength inside the TEM cell can be adjusted.
