摘　　要：为实现特定的伪装遮障面电磁散射特性,受频率选择表面与吸波材料复合技术的启发,提出了在均匀有耗介质布(伪装遮障的基础布)表面涂覆周期性导电薄层(如"十"字形、方形和耶路撒冷形)的设计思路。采用周期FDTD算法分析了垂直入射时此类结构的电磁散射特性,并最终提出了能够在2～18GHz范围内基本满足能量反射率在20%～25%、透射率<30%和吸收率>45%的介质布参数配置方案。In order to realize the special electromagnetic scattering from camouflage screen,inspired by the compounding technique frequency selective surface(FSS) and radar absorbing material,the application of different shape(such as cross,square and Jerusalem) periodic conductive thin layers on dielectric cloths(basic cloths of camouflage screen) was proposed.Electromagnetic scattering propertise from these structures for normal incidence was analyzed by periodic FDTD algorithm.Some design schemes of dielectric cloths were finally presented,which basically satisfy the requirement of energy reflectivity between 20% and 25%,transmittivity less than 30% and absorptivity more than 45% within the range of 2-18GHz.
