Abstract: Edge-based finite element method-boundary element method (FEM-BEM) for the computation of three-dimensional (3-D) electromagnetic fields at high and low frequencies is presented. A novel H-A model that includes the differential and integral equations for wide-band electromagnetic problems is described. An edge element method is implemented to discretize the proposed formulation. A surface edge element method (SEEM) for surface of arbitrary shape targets is derived according to the geometrical properties of the basis functions. Unlike traditional electromagnetic formulations, the major coefficients of the proposed formulation in this model are frequency independent and hence the model can be used to solve electromagnetic problems over a wide range of frequencies. The proposed method is implemented to compute: 1) the electromagnetic induction problems at low frequencies and 2) the scattering fields at high frequency. Results from established methods are used to validate the proposed method.
