A one‐step leapfrog weakly conditionally stable finite‐difference time‐domain method for modelling drude dispersive models is developed. Numerical results show that its stability condition remains invariant with respect to that in lossless media. The new algorithm is applied to efficiently investigate the transmission properties of a graphene sheet and a graphene‐based frequency selective surface.
