Constantly on-going changes in new technologies applied in modern vehicles introduce many challenges in the automotive electromagnetic compatibility engineering. So far, the currently implemented EMC requirements and methods present sufficient performance. However, they do not illustrate thoroughly an actual automotive environment. They tend to focus on the EMC validation of each system individually without always considering other possible influential factors and coexisting systems. Aim of this paper is to introduce an EMC system investigation platform using a simplified model that demonstrates an automotive environment in order to point out the importance and scale of significance of various parameters. In this paper, the structure of the introduced three-point model is first described and explained. Then, experiments are presented in order to point out the influence of selected macroparameters. Finally, suggestions for further extension of the model through Monte Carlo simulations are proposed with a brief presentation of a modelling procedure.

Due to the on-going changes in modern technologies, deeper investigation of the complex automotive electromagnetic environments is necessary. Since conventional standardized testing methods are lacking characteristics met in real automotive electromagnetic environments, a risk-based electromagnetic compatibility approach can conclude to detection of potential electromagnetic interference threats. A measurement of a real automotive electromagnetic environment is proposed and investigated using two different measurement methods addressing the temporal and spatial variations of the electromagnetic environment. This investigation reveals the complexity of real electromagnetic environments and the difficulty of them being sufficiently described to warrant electromagnetic compatibility due to continuously varying parameters over space, time, and frequency. The random-walk technique is applied and compared with a discrete static measuring technique of acquiring data. Examination of the collected data is made along with discussion on their possible application through statistical tools.

This paper presents shielding effectiveness measurements of board level shielding materials using the dual vibrating intrinsic reverberation chamber. Various sized board level shielding materials mounted on specifically designed printed circuit boards are examined in order to evaluate the shielding performance in each case. Experiments presented in this paper aim to investigate the effect of appropriate mounting of the test samples before performing a shielding effectiveness measurement, as well as to compare the shielding mechanisms of these kinds of materials. Additionally, based on the obtained measurement data, a discussion on the definition of shielding effectiveness and the effect of the aperture on the coupling of the two cavities of the dual VIRC is briefly conducted.

Due to the increasingly implemented electronic devices in modern applications, the electromagnetic environments become more and more complex. Therefore, there is need for such environments to be evaluated, so that potential electromagnetic compatibility issues can be identified and solved. So far, standardized methods have been using conventional measuring techniques such as e.g., superheterodyne receivers, oscilloscopes, etc. These types of devices depict the output data measured over frequency or time, determining the electromagnetic behavior of a system under test in a single domain. Although they are suitable for laboratory tests, a proper description of the real intended electromagnetic environment, where the device would be placed, requires a more careful analysis, especially in order to implement the risk-based EMC approach. Experiments performed in a vibrating intrinsic reverberation chamber representing an example harsh environment, using four different measuring methods show the receiving capabilities of each for better understanding on how an electromagnetic environment could be characterized.
