Authors: Drozdova A. A., Komnatnov M. E.

Annotation: We evaluated the induced electromagnetic interference on a monopole and a microstrip line generated by an electrostatic discharge sourсe in a small-sized TEM-cell. Analytical, quasistatic, and electrodynamic models are presented for calculating the waveforms and amplitudes of currents and voltages induced on the monopole and the microstrip line. These waveforms are presented for analytical, quasi-static, electrodynamic calculations, and measurements. The maximum deviations of analytical and electrodynamic calculations results for the monopole and the microstrip line are 25 and 9%. An approach is presented for using half of the coaxial cell as a matching device between the electrostatic discharge source and the TEM-cell. The results of calculations and measurements agree well, which indicates the possibility of using a small-sized TEM-cell and half of the coaxial cell. These devices could be helpful to study the effect of electrostatic discharge -generated electromagnetic interference on integrated circuits, electronic component base, and small devices in general.
