Based on negative refractive index materials' constitutive relations, the finite-difference time-domain(FDTD) formulations are obtained by using piecewise linear recursive convolution(PLRC) method. It is named PLRC-FDTD method. Then the PLRC-FDTD method is applied to calculate radar scattering sections(RCS) of perfectly conducting cylinder coated with negative refractive index materials (NIRM). The effect of the plasma parameters on the radar scattering cross sections is investigated and some numerical results are obtained. The results indicate that an appropriate NIRM coating may efficiently reduce the RCS of a metallic target.
