Abstract

Abstract

The equations of piecewise linear recursive convolution(PLRC) using finitedifference time-domain(FDTD) method for negativerefractive index materials are presented. The PLRCFDTD method is used to simulate the interaction of electromagnetic wave with negative refractive index materials and calculate the electromagnetic wave reflection coefficients of conductive plate coated with negative refractive index materials. Numerical results indicate that negative refraction index materials cover can greatly reduce the echo energy of targets. The higher the collision frequency and the lower the oscillation frequency, the better the absorption effect. And reflection coefficients are affected by collision frequency, oscillation frequency and distribution form of the material．
