Laboratory for generation and measurement of electromagnetic pulse parameters: current state and prospects of metrological support in the field of pulsed electromagnetic fields

Ensuring the uniformity of measurements of pulsed electromagnetic factor parameters is critical for improving the reliability of interference immunity testing of aviation, rocket and space equipment, and information and communication technology equipment. This article provides an overview of electromagnetic pulse measurement instruments used in the Russian Federation, indicating their types and main metrological characteristics. Traceability of these measurement instruments to state primary standards of units of pulsed electric and magnetic field strengths, high pulsed electric voltage, and pulsed current is ensured. A comparative analysis of the state of metrological support for pulsed electromagnetic fields, currents, and voltages in Russia and abroad is conducted. The paper formulates key areas for improving the reference base for the metrological support of prospective types of pulsed electromagnetic field measurement instruments. The choice of a pyramidal TEM-cell (GTEM-cell) as a field-generating system of standard facilities for reproducing long-duration pulsed electric and magnetic fields with rise times in the tens of picosecond range is justified. Its geometric parameters and structural elements are calculated, and the amplitude-time range and uncertainty of unit reproduction are estimated. Standardizing the dynamic performance error of measuring instruments in the picosecond range has been identified as a prospective direction for further research in ensuring the uniformity of pulsed electromagnetic field measurements.
