“…For the low frequency range and low impedance cable bundles, we globally observe constant currents versus frequency in measurement and simulation. This confirms the analysis in [10] and is in contradiction to the increasing currents over frequency which are provided in [8]. The measured results of the GPS cable bundle currents in Fig.…”

HIRF transfer functions results are rarely available to the public. Generally, the data provided in applicable guidance material are used for estimation of internal HIRF environment in an air vehicle. An exemplary set of HIRF transfer functions for a small aircraft is presented here. Results for the aircraft (10.4-m wingspan and 8.3 m of length) are compared with regard to state of the art approaches applied for aircraft HIRF certification campaigns. This is done in appropriate frequency ranges and by the use of applicable test methods with regard to requirements in place. For all major types of contemporary test methods, results are generated by measurement and numerical computer modeling. Principles of outcomes are discussed and compared to current practice in place. This concerns the shapes of the transfer functions on one hand and the order of magnitudes of obtained levels on the other hand. The obtained results show significant deviations from generic transfer functions currently applied in aircraft industry. The coupling to the interior of the aircraft observed here was higher than indicated by the applicable generic transfer functions. Numerical computer modeling is used here to verify the obtained outcomes by principle.Index Terms-Direct current injection (DCI), high intensity radiated fields (HIRF), low level direct drive (LLDD), low level swept current (LLSC), low level swept field (LLSF), method of moments (MoM).

“…Above 15 MHz and up to the first internal conductor resonance, the current has a quite horizontal shape due to the dominant inductive load. The resulting current is fundamentally influenced by the conductor and the loads [24]. The same parameters are decisive for the possible existence of the so-called 20 dB/decade rolloff (see [1,Sec.…”

An entire set of high-intensity radiated field transfer functions including the main types of contemporary test methods is presented. Consequently, the applied frequency range for this task expands over many decades, from the kilohertz range up to 40 GHz. A major aim is to demonstrate the application of numerical computer modeling for such a task. Results of measurements and various solvers are compared to each other. As the activity serves also for the validation of such applications, the scenario is investigated by the use of a fuselage model with limited complexity. Index Terms-Asymptotic, computational electromagnetics (CEM), direct current injection (DCI), finite-difference time domain (FDTD), high-intensity radiated fields (HIRF), low-level direct drive (LLDD), low-level swept current (LLSC), low-level swept field (LLSF), method of moments (MoM), power balance (PWB).

“…Essentially, the interference current is injected into the cable of the equipment to substitute for radiation susceptibility test [1,2]. As a kind of complementary method, the core of the BCI research is how to keep the equivalence with the radiation test method in broader application range and higher precision [3][4][5][6].…”

This paper presents a new kind of differential-mode current injection test method. The equal response voltage on the cable or the antenna port of the equipment under test (EUT) is regarded as equivalent principle for radiation and injection test. The injection and radiation response analysis model and the injection voltage source extrapolation model in high intensity radiated field are established. The conditions of using differential-mode current injection as a substitute for radiation are confirmed. On the basis of the theoretical analysis, the function and structure design scheme of the directional coupling device is proposed. The implementation techniques for the single differential-mode current injection method (SDMCI) and the double differential-mode current injection method (DDMCI) are discussed in detail. The typical nonlinear response interconnected systems are selected as the EUT. The test results verify the validity of the SDMCI and DDMCI test methods.
