Prediction of Dissipation in Electronic Components by Computing Electromagnetism

Electromagnetism in electronic components becomes relevant in high frequencies, where induced currents cause a deviation of the response from “slow” operation conditions. As electric field and magnetic flux alter in time, dissipative effects occur due to different mechanisms such as viscous deformation and Joule’s heating. Indeed, dissipation is an energy loss and thus the industry tries to minimize this effect by amending engineering design. For a better prediction of an electronic system with many components, a detailed multiphysics simulation fails to be feasible. Hence, by using a reduced order modeling, we discuss how to involve energy dissipation in electromagnetism computations with the finite element method (FEM) and propose a connection with an industrial quality measurement out of such computations.
