The paper presents a statistical approach to estimate the risk of an electronic system to intentional electromagnetic interference. The keywords Smart Grid, Industry 4.0 and Internet of Thinks leads to complex system with many dependencies between each electronic system. A faultless function of that complex systems is needed, which is achieved only with a cost efficent protection. That only can achieved with a stastical estimation of the risk to find the weakest link in the chain.

In the potential-current representation, transmission-line parameters in the Transmission-Line Super Theory (TLST) do not have a direct physical meaning – they are gauge dependent. The transmission line parameters also contribute to the total radiated power of the lines. The attempt to quantize radiation locally, fails because radiation describes a long-range (integral) interaction. However, it can be stated that at stronger inhomogeneities the local contributions to radiation increase.

A numerical method is presented which is capable to compute the electromagnetic fields created by the current of a spatially extended lightning channel. The coupling of these fields into simple models of aircraft fuselages is investigated, where the electric material parameters of the fuselages correspond to those of realistic layered carbon fiber composite.

The validation of GTEM cells, which are an established alternative for an open area testside and are used for electromagnetic emission and susceptibilty tests, is performed in time domain with a specifiedl transient pulse with a double exponential shape. This paper provides a new validation method, wich is applicable for any transient pulse and presents further investigations of a GTEM cell in frequency domain.

Radiated electromagnetic fields from a PCB can be estimated when the source current distribution is known. From a measured near-field, the PCB source current can be found. Solving the given inverse problem with a system of linear equations and complex near-field data it can be very sensitive to noise. Regularization methods and an adjusted preconditioning can increase the accuracy. In this publication, an improved radiation model creation approach based on complex near-field data is presented.

The ever increasing use of PEDs (passenger or portable electronic devices) has put pressure on the aircraft industry and operators to reevaluate established restrictions in PED-use on airplanes in the last years. This paper presents a measurement campaign in an Airbus A320. Although there were many measured emissions from 150 different PED (including many attached cables; operated by 69 test passengers) detected within the cabin, no disturbance signals were detectable at the aircraft antennas.

One of the issues in Electric Vehicle (EV) is to control the electromagnetic noise, so that both High Voltage (HV) power drive system and Low Voltage (LV) systems (like communication-, infotainment-, safety systems, etc.) coexist in harmony and perform their respective functions efficiently. In this article, techniques to analyse HV cables and how to design better shielding is discussed, which may help to design better layouts for coexistence of HV and LV in EV. Aim is to assist system designers

A near-field measurement based pre-compliance method is provided for predicting emission below 30 MHz in a CISPR-25 test set-up. The Huygens principle by defining an unclosed Huygens' surface is applied for field prediction. Near-field measurements are only conducted for several locations over a table surface and a static electric field formula is used for field distribution estimation. The difference of the predicted E-field at 1 m distance is within 4 dB compared with full-wave simulation.

Test setups required for different immunity test methods based on ISO 11452-2 (ALSE) and ISO 11452-4 (BCI) are similar. However, lack of knowledge regarding the impedance of the tested component, makes it impossible to find the equivalent current to be injected by the BCI probe and a good match cannot be achieved. In this paper, three approaches are proposed to estimate the termination impedance indirectly by using different current probe.
