Applying Finite Element Method–Dirichlet Boundary Condition Iteration to the Computation of Coupling Factors for a 3-D Human Model

Abstract

The hybrid FEM-DBCI numerical method is proposed for the computation of coupling factors between time-harmonic magnetic fields and human bodies. Characteristics are highlighted which make FEM-DBCI very suitable to perform such computations. Several coil geometries are considered (circular coils) at low frequency. A simplified model of the human body is assumed as suggested by IEC standards. Details of the method are highlighted, and numerical results are also provided.
