METAMATERIAL 1D SIMULATION USING FDTD METHOD

Metamaterial is a double negative material where the effective permeability and permittivity are negative. So if we hit any Gaussian wave on the surface of DNG material then some part is reflected and some are transmitted.As in this code we see that there is some sudden frequency where it can only transmit signal, so that frequency where the both mue and epsilons are negative. The first graph shows the response of different times steps how the metamaterial behaves and second graph shows its transmission parameter at different frequency.
