摘　　要：从电磁波的波动方程出发，分析二维周期结构材料对入射电磁波（光子）的散射，计算不同散射单元尺寸和形状下散射光强的空间分布，提出了一种防激光制导武器打击伪装材料结构设计方法。该方法利用材料特殊结构，使得目标表面反射的激光能量发生角度偏转，从而增强对激光的有效散射，达到伪装的目的。解析结果表明，该材料结构设计方法是激光伪装技术的有效途径之一。Based on the wave equation of electromagnetic wave, the scattering of the incident light by 2D periodic structure is analyzed, and the distribution of scattering light intensity under different size and shape of scattering units is calculated, so that a design method of a kind of anti-laser camouflage material is presented. The method utilizes the special structure of material to make the laser energy angle reflected on the target surface changed, and then increase the dispersion of laser. The results indicate that the method is one of the effective techniques in laser camouflage.
