Abstract:

High accuracy approximation of mixed finite element for 2d  Maxwell equations are studied in this paper. For the solution of mixed finite el ement of  2d Maxwell equations, the \$L\+2\$norm convergence rate can be in creased  from O(h\+2) to O(h\+4) by postprocessing if taking the first Nedelec f inite element space on the uniform rectangular meshes.

Key words: Maxwell equations; Mixed finite element; Superconvergence; Postprocessing
