High Fidelity Electromagnetic Simulation: Bridging Aerospace Innovations to Diverse Industries
Sebastian Soldwisch
EMA3D
Since the 1970s, Electro Magnetic Applications (EMA) has been at the forefront of solving EMI/EMC challenges for aerospace and defense platforms globally. The technology and fidelity leveraged to solve EMI/EMC simulations have increased by orders of magnitude, evolving from using punch cards to mesh aircraft bodies to solving simulations with over a billion mesh elements in a single day. Through the pursuit of including full aerospace platform mechanical geometry CAD and thousands of cables in a single simulation, EMA has developed capabilities in Ansys EMC Plus that are now applicable across various industries, from automotive to high tech, industrial to medical, and beyond. This talk will explore the evolution of full platform electromagnetic simulation, showcasing how EMA has integrated simulation and measurement to support EMI/EMC certification over the decades. Key technologies include the hybridization of full wave FDTD with multi-conductor transmission line solvers and multi-GPU acceleration, enabling high fidelity correlation to measurements on complex platforms. The insights gained from simulating aerospace and defense platforms to address challenges like lightning, EMP, and MIL-STD-461G are now being applied to other sectors for certifications such as radiated/conducted emissions and susceptibility. What are the differences in our modeling approaches for these industries and what level of fidelity is needed to make engineering decisions that lead to a higher quality product but still cuts down design and timeline costs.

Satellite-level EMC testing, being a late-stage verification, can be costly and time-consuming due to very complex setup and need of specific test facilities. State-of-the-art numerical simulations are essential tools for anticipating potential electromagnetic compatibility (EMC) issues in the early stages of satellite design. The risk of RF compatibility issues between satellite components can lead to significant time impacts and additional costs. Full-wave analysis can mitigate these EMC risks and reduce the reliance on final testing, providing a more accurate prediction of system performance. Additionally, verification through simulations enhances confidence in system reliability by enabling the modelling of EMI effects that, in some cases, cannot be tested due to setup inaccuracies or limited accessibility during the final integration of the satellite. This work presents EMC modelling for an Earth Observation satellite designed and manufactured by Thales Alenia Space, leveraging ANSYS suite solutions.
