6. Hybrid techniques

During the course of a design project, constraints in other fields such as thermal or mechanical engineering, or simply an assessment of costs or weight, or a change in technical solutions, may call into question the choice of an EMC protection solution.

For example, the need for ventilation holes in a piece of equipment may call into question its EMC shielding logic, or the non-linear operation of a power converter may imply an inadmissible source of radiation when installed in our system. In such cases, data exchanges between trades are used to assess the compatibility of proposed solutions.

In the real world, these types of physical coupling involve different phenomena at the same time. The answer to a multiphysics optimization problem is far from simple, but in recent years a number of simulation techniques have attempted to provide...
