• Resumen

  • In this paper, the energy-conserved splitting Legendre Galerkin method and energyconserved splitting Legendre collocation method for Maxwell�s equations in two dimensions are proposed. The schemes are energy-conserved, unconditionally stable, and can be implemented efficiently. The both methods are of second-order convergence in time.

    The high order error estimates in space for the two methods are also obtained. For the EC-S-LC method, an identity of the discrete divergence of electric fields is also obtained.

    Numerical examples are provided to confirm the theoretical analysis
