This contribution investigates the approximation of a well-established immunity test method for electronic equipment by an alternative test method, which so far has only been applied to electronic equipment in aircrafts. The alternative method can provide a similar test environment under certain test conditions, yet offers additional advantages with respect to practical criteria like time and cost saving. It is thus promising for further industrial applications, such as the automotive industry.

The use of high-power electromagnetic sources to disrupt or maliciously damage electronic devices in critical power infrastructures is growing in concern. This paper presents a vulnerability study where a digital protection relay is exposed to high-power electromagnetic interference signals. The results reveal failures of this device that can impact the operation of power substations.

In this artice two loopantennas in freespace are modeled and simulated in a numerical field calculation program. To verify the results, two approaches based on equivalent electrical circuit diagrams (ECD) were investigated. One approach based on the ECD of a real coil and another is based on the input impedant of the antenna. The comparison of the results of the simulation and the analytical calculation of the ECD from the input impedance of the antenna showed a very good agreement.

In artificial ventilation of neonates uncuffed endotracheal tubes are commonly used. The unknown leakage hampers the detection of spontaneous breathing. A new method to measure respiration by using antennae has recently been presented. A respective setup is investigated numerically and experimentally. Both approaches show that the method seems capable of allowing a contactless triggering to synchronize ventilation. The results are compared to derive a better understanding of influencing factors.
