摘      要:

       In this paper, we intend to develop a weak Galerkin (WG) finite element method for solving the indefinite time-harmonic Maxwell equations. By showing an analogy of G ̊arding inequality and a posteriori estimate about the error, we first prove the well-posedness of the WG method. Then by deducing an error equation, we achieve optimal a priori error estimates in both the energy norm and the L2 norm. Finally, we carry out some numerical experiments to confirm the theoretical conclusions.
