“…Based on this case study, it can also be concluded that although standalone active devices have been EMC compliant, EMI issues could still occur when these active devices are inter-connected with passive devices [1] [5].…”

In this paper, a case of electromagnetic interference (EMI) in medical display systems is reported. It concerns the nearby use of an electrosurgical knife disturbing video-monitors, interconnected by Ready-Made Connecting Devices (RMCD), in a surgery room. Based on full wave simulations, three parameters of these RMCD in a medical display installation, including the total length, location of connecting and the number of GND reference -wires, are identified. The simulation results demonstrate that these parameters can not only lead to EMI but are also influencing the characteristics of such EMI.

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.

“…development processes struggle to keep up with technological evolution [1]. Moreover, the rising cost of certification and achieving full compliance in some industries such as maritime, along with accessible Commercial Off The Shelf (COTS) equipment that may not comply with maritime EMC standards [2], signals the need for a new approach. Therefore, a risk-based approach for EMC has been put forward as an alternative.…”

Over the last decade, awareness has grown that compliance to EMC standards does not necessarily imply that all properties of a system, such as reliability, safety, and security, are adequately assured when the system is exposed to electromagnetic disturbances. While the application of a risk-based approach has been proposed to overcome this issue, a methodology to demonstrate that the employed risk-based activities provide compelling arguments and evidence to assure the properties of interest seems to be missing. In this paper, the application of assurance cases and associated activities in demonstrating properties like safety and security of systems in the presence of electromagnetic disturbances is explored by using Goal Structured Notation (GSN) to present the structure of the assurance argument.
