In adition to the practical execution of EMC tests, we are also able to perform electromagnetic (EM) field simulations. This allows us to quickly and cost-effectively evaluate different design variants and modifications for electromagnetic effects in the early design phase and propose changes and improvements to our customers without the need for real prototypes.
Simulation at EMCC
Theroretical background, many years of experience, a daily routine in performing EMC measurements and tests on complex systems or complete platforms and broad inventory of necessary equipment enable us to make plausibility assessments and cross-validations of our simulation results.
You profit from:

- Significant time savings
- Theoretical and numerical analyses of the coupling efeects, analysis and simulation of the protection measure, deign support and reviews
- Focus applications include HIRF, Lightning Effects, NEMP and Antennas
HIRF - High Intensity Radiated Fields
Numerical simulations concerning the effects of HIRF can be employed in all stages of aircraft design process. In early stages it can be used to estimate the levels of internal electromagnetic environment; later to evaluate impact of design modifications and finally to complement measurement campaigns to achieve HIRF certification. For the last case, EM simulation is employed to investigate influence of aircraft illumination at incident angles that are not covered by the ground testing and to evaluate differences between a ground level measurement setup and the flight, start and landing scenarios.
The characterization of antennas over intended frequency including determination of the key parameters such as beamwidth, radiation pattern and side lobes, antenna factor and antenna gain.
Current distribution of a horn antenna at 4.8 GHz:
In order to define the proper lightning requirements EMCC can perform a basic simulation of the aircraft using CAD drawings and other information to estimate the lightning current distribution in aircraft structures and to determine the estimated levels of transients appearing at interfaces of the electronic systems in already early stages of the design, after modifications or as a part of formal aircraft certification process.
