Electromagnetic fields and circuit simulation

Often, devices can be simulated sufficiently accurate as electrical circuits, i.e., by network models. However, the increasing frequencies and the decreasing size forces designers to account for wave propagation effects, eddy-currents, ferromagnetic saturation and hysteresis. Some effects can be represented by order-reduced equivalent models that are embedded in an electrical circuit.

However, the representation of field-dependent nonlinearities and hysteresis effects is not straightforward. Complex 3D field models are required, e.g. discretized with classical finite elements (FEM) or isogeometric analysis (IGA). Therefore hybrid field/circuit models are a relevant research topic on its own.
