abstract = {<p style="text-align: justify;">In this paper, nonconforming mixed finite element method is proposed to
simulate the wave propagation in metamaterials. The error estimate of the semi-discrete scheme is given by convergence order&nbsp;$\mathcal{O}(h^2)$, which is less than 40 percent
of the computational costs comparing with the same effect by using Nédélec-Raviart
element. A Crank-Nicolson full discrete scheme is also presented with&nbsp;$\mathcal{O}(τ^2 + h^2)$ by traditional discrete formula without using penalty method. Numerical examples
of 2D TE, TM cases and a famous re-focusing phenomenon are shown to verify our
theories.</p>},
