Transverse electromagnetic (TEM) waveguides are predominantly used for emission and immunity tests. General requirements for TEM waveguides are given by the IEC 61000-4-20. Annex C of the IEC 61000-4-20 specifies immunity tests based on high-altitude electromagnetic pulses with a double exponential waveform. This waveform’s shape is sufficiently de...

The imaging capability of conventional lenses is mainly limited by the diffraction of light, and the so-called superlens has been developed allowing the recovery of evanescent waves in the focal plane. However, the remarkable focusing behavior of the superlens is greatly confined in the near-field regime due to the exponential decay of evanescent w...

... Given the continuous deterioration of the modern electromagnetic environment, in addition to the well-established single-tone time-harmonic field RS tests [1], [2], growing attention has been directed toward the susceptibility of electric systems under the illumination of pulsed electromagnetic fields with large amplitudes and rich frequency components. Indeed, depending on applications, both relevant EMC normative documents [3], [4], [5], and pioneering research works [6], [7], [8], [9] have envisioned pulsed RS testing approaches. These approaches aim to generate canonical pulsed field environments such as high-altitude electromagnetic pulse (HEMP), ultra-wide bandwidth (UWB), and intentional electromagnetic interferences (IEMI) within laboratory settings. ...
In this article, we propose a nonintrusive pulsed radiated susceptibility testing approach based on the long-line crosstalk setup. The objective is to reproduce the pulsed electromagnetic field coupling effect for wiring harness systems. The proposed test setup explores the crosstalk between parallel wires and imposes an additional pulse-driven wire to couple the interferences onto the wire under test. The transmission line model is exploited to represent both crosstalk and the pulsed field coupling process, demonstrating that equivalence can be achieved within a limited clearance time in general, provided the driven wire exceeds a critical length. In addition, rigorous equivalence can be obtained for particular incidences, such as broad-side illumination and end-fire excitation, under the condition of matched auxiliary equivalent terminals. Comparing this to state-of-the-art pulse injection approaches, the crosstalk-based testing method ensures the exact reproduction of field coupling effects without necessitating driven pulse predistortion, this characteristic underscores its robustness for pre-compliance pulsed field radiated susceptibility testing. Additionally, by considering a canonical double exponential interference, a pilot experiment is conducted to verify the equivalent rationale and feasibility of the proposed approach.
