“…Usually the differential RF currents are measured by current probes [5], [6]. But in our experiment this is not appropriate because the probe with output coaxial cable becomes a part of the measuring object arrangement.…”

The paper deals with the analysis of induced current of differential loops of transmission lines during immunity test against electromagnetic field measurement. The influence of geometrical configuration of cabling arrangement on induced current values is surveyed. The problem is described for the case of a short two-wire line creating differential mode loop. The current induced at both ends of the line is the characteristics observed in the performed studies. The comparison between the results of measurements on real physical line, numerical simulations and analytical solution is presented.

Abstmct-Bulk current injection and field coupling are analytically compared in order to ascertain if current injection tests are adequate for susceptibility assessment of electronic equipment. Transmission line theory is adopted for modelling wiring harnesses, and the equivalence is discussed by comparing the effects that the two kind of excitation techniques produce at line ends. General results are obtained, which are not affected by any assumptions on the equipment under test. It is shown that, from the theoretical point of view, injection by means of two current probes allows equivalence with any radiated plane wave excitation. The equivalence is achieved by controlling the clamp voltage in order to match the incident field characteristics.

“…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]. Although the traditional BCI method has been proposed for nearly half a century, there are still insufficiencies to substitute for the high intensity radiated field (HIRF) effects test.…”

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.
