In order to increase to a greater extent the calculation accuracy for complex electromagnetic fields in the modern physics, a hybrid finite element method (HFEM) is presented for analysis and simulation of complex electromagnetic fields. In the paper, the hybrid finite element method (HFEM) with high accuracy is introduced, and the complex electromagnetic field in an electromagnetic device has been calculated successfully by the hybrid finite element method (HFEM) and the electromagnetic properties of the electromagnetic device under the specific work condition is evaluated. It is shown that the method can provide a much more accurate calculation and good agreement between the computed values and the experimental values.

Abstract The rigid finite element method (RFEM) has been used mainly for modelling systems with beam-like links. This paper deals with modelling of a single set of electrodes consisting of an upper beam with electrodes, which are shells with complicated shapes, and an anvil beam. Discretisation of the whole system, both the beams and the electrodes, is carried out by means of the rigid finite element method. The results of calculations concerned with free vibrations of the plates are compared with those obtained from a commercial package of the finite element method (FEM), while forced vibrations of the set of electrodes are compared with those obtained by means of the hybrid finite element method (HFEM) and experimental measurements obtained on a special test stand.
