A new finite element formulation for the three-dimensional electromagnetic fields using second order edge elements is developed. Edge elements are capable of suppressing the suprious modes. One of the authors has proposed the first order edge element for a hexahedral shape. Additional variables are required due to Lagrange multipliers as to suppress the effect of the suprious modes. The resultant discretized equation cannot be solved as an eigen equation. In this paper, new second order edge elements are proposed. To verify the validity of the elements, resonance frequencies and frequency responses of a circular cylindrical resonator model are calculated and are compared with the ones calculated by using the first order edge elements.
