This paper presents time-domain electromagnetic interference measurement methodologies for comprehensive characterization of the frequency band used by subsurface radars in interplanetary missions. These methodologies combine EMI receiver and oscilloscope measurements, enabling statistical analysis and overcoming the limitations of traditional frequency-domain approaches in predicting Radio Frequency Interference in the operating bandwidth. The presented measurements are conducted under stringent conditions, addressing the extremely low-level electric field requirements from 6 to 12 MHz frequency band.
EMC ANALYSIS ON THE INTEGRATION OF AN ELECTRIC PROPULSION ARCHITECTURE
Michael Ridel, Houssem Chebbi, Samuel Bonnard, Michel beltramini
ONERA, France
The aim of this paper is to analyze the impact of constraints linked to the integration of an electrical power architecture at system level. Based on the description of a process used to define and evaluate the characteristics of an electrical architecture, the multidisciplinary effects of the various integration constraints (electromagnetic, thermal, etc.) linked to the power increase are identified. Based on these findings, a multi-physics pre-analysis is carried out to assess the effects of the installation choices on its electromagnetic response.
Analysis of Common-Mode Coupling Between Cables on Composite Aircraft Panels
Marcos Quílez, Ferran Silva
Universitat Politècnica de Catalunya, Spain
The replacement of metallic fuselage panels with conductive composite materials affects electromagnetic compatibility (EMC) due to differences in electrical conductivity and joint connections. This study examines common-mode coupling between cables placed on metallic and conductive composite material ground planes using different measurement setups. Results indicate similar coupling above 1 MHz, while below this frequency, composite panels exhibit higher coupling due to poor electrical contact at junctions. A modified setup confirms that increased coupling is primarily caused by joint connections with poor conductivity in addition to intrinsic composite material properties. These findings provide insights for grounding techniques in modern aircraft and for defining measurement setups.

As aeronautical products continue to evolve and become more intricate, the process of modeling the Equipment Under Test (EUT) also becomes more advanced.
This article explores the prediction of ElectroMagnetic Compatibility (EMC) susceptibility in aeronautical systems by developing an initial virtual EMC testing framework using IBIS (Input/Output Buffer Information Specification) models.
This virtual environment represents a first step toward a digital twin for EMC qualification, enabling the simulation of electromagnetic phenomena and helping to identify and resolve EMC issues early in the design process.
