Interaction of Low Frequency Magnetic Fields with Car Chassis

摘要

The subject of this paper is numerical modeling of car chassis made of thin highly conductive and magnetic materials and exposed by low frequency magnetic fields. Incorporating reduction of thickness of sheet into Maxwell equations leads to approximate boundary conditions, written for normal components of magnetic fields of free space. These magnetic fields are radiated by single and double layer magnetic charges, located on the interface surface. Resulting equations are solved via Method of Moments. Numerical simulations are compared with measurement data for plane sheets made of different materials. Excellent agreement is found in all considered cases. Computations of magnetic fields, radiated from supply cable in the car illustrate capabilities of the method.
