3D modeling of shielding structures made by conductors and thin plates

摘要

The aim of this article is to present a method of modeling shielding structures made by conductors and thin plates. Short circuited conductors placed in a magnetic field created a field which is opposite to the source. To combine these structures with a classical shielding plate seems to be a good solution. The resolution is obtained coupling FEM to electrical circuit analysis and including multiply connected regions. The thin plate is modeled using shell element. The method is used to solve a practical problem of electromagnetic compatibility. Comparisons between numerical results and measurements are done in order to confirm the accuracy of the chosen method.
