Discontinuous Galerkin Finite Element Time Domain Method for Analysis of Ferrite Circulator with Non-conforming Meshes
In this paper, a Discontinuous Galerkin finite element time-domain method (DG-FETD) based on non-conforming hybrid meshes is presented for analysis of the ferrite device. The DG-FETD method with explicit difference scheme is firstly used to analyze the electromagnetic characteristics of complex medi...

| description | In this paper, a Discontinuous Galerkin finite element time-domain method (DG-FETD) based on non-conforming hybrid meshes is presented for analysis of the ferrite device. The DG-FETD method with explicit difference scheme is firstly used to analyze the electromagnetic characteristics of complex medium such as ferrite material to reduce memory requirement and computational time. The recursive convolution (RC) method is applied into DG-FETD to deal with the constitutive relation of ferrite material. What’s more, the non-conforming hybrid mesh method with tetrahedron-hexahedron is employed to improve the flexibility and accuracy in mesh processing and reduce the number of unknowns. Numerical results show the efficiency of the proposed method. |
