“…It is acceptable even for currents induced on inner conductors, which could permit the use of predicted values for determining levels for the pin injection test employed in lightning certification [33]. Likewise, good results for DCI validation have also been achieved mainly for surface current density and even for currents induced along over-braids in previous works as [34][35][36][37][38][39], but with no validation of currents induced on inner conductors.…”

In this paper, the effectiveness for inferring the responses to electromagnetic threats of the finite difference time domain method combined with a multi-conductor, multi-shield, and multi-branched cable harness transmission line solver is validated by comparing simulation results with measurements performed on an equipped cockpit partially made by carbon fiber composite. A complete lightning indirect effects and high-intensity radiated field testing campaign was carried out in this cockpit within the scope of the European research and technology project Clean Sky 2 whose main goal is to reduce the aviation environmental impact by, for instance, building low-weight aircrafts with the increasing use of carbon fiber. Simulations are performed with EMA3D and MHARNESS obtaining very good agreement with measurements for a variety of observables and in a wide frequency range, thus proving the predictive capacity of these numerical methods for estimating the electromagnetic behavior of complex structures.

“…It employs the injection of currents onto the conducting surface of a DUT using voltage or current sources as injection adapters, whereas additional termination adapters realize a current return path via a ground plane (Leat, 2007). Instead of a ground plane as return conductor, a coaxial return structure enclosing the DUT is likewise possible (Pérez et al, 2019). Despite the introduction of DCI several decades ago, its correlation to other EMC test methods like HIRF is still subject to contemporary research, see Rothenhäusler et al (2019Rothenhäusler et al ( , 2023, Wang et al (2020), Ückerseifer et al (2019, 2021, 2023).…”

Abstract. This contribution discusses the approximation of radiated by conducted immunity tests by the example of High Intensity Radiated Field (HIRF) and Direct Current Injection (DCI) based on a surface current analysis. For this purpose, Characteristic Mode Analysis (CMA) is applied to provide basis functions for a surface current expansion in Characteristic Modes. Via a matrix-based basis transformation algorithm involving Characteristic Mode data of both HIRF and DCI test setups, suitable DCI surface currents are derived. The approximation of HIRF surface currents by the computed DCI surface currents is analyzed for exemplary DUTs over a broad frequency range. Within this frequency range, those DCI frequencies leading to an optimal approximation of the HIRF current are determined. Concerning practical issues in DCI testing, the influence of DCI adapter parameters on the surface current approximation is elucidated. The numerical results show that DCI can approximate HIRF at low frequencies largely independent from the DCI adapter setting, whereas at high frequencies an approximation is difficult to realize.
