Abstract :
The standard finite-difference time-domain equations can model propagation of wave in dispersive media. However in case of plasmas and metals, the negative values of permittivity makes the standard time iteration scheme unstable. We describe a numerical technique to solve Maxwell´s equations in frequency domain in this case.
