多针晶须吸波材料是一种新型的隐身纳米复合材料，其吸波性能与材料的微观结构密切相关。考虑到这种有趣的复合材料的微观结构，合适的模拟模型的可用性是重要的，它的设计和性能优化。本文提出了一种新的仿真模型，用于多针晶须吸波材料的微结构设计。首先，根据等效介质理论和传输线法建立了计算模型。将计算曲线与已有的实验数据进行了比较，两者吻合良好，表明该模型可用于该类RAM的组织优化。最后，利用该仿真模型和粒子群算法对一种三层多针氧化锌晶须（M-ZnOw）吸波材料的微结构进行了优化设计，结果表明微结构设计对提高该吸波材料的吸波性能具有重要意义。
Multineedle whisker radar absorbing material (RAM) is a new kind of stealth nanocomposite, whose radar absorbing property is a function of microstructure. The availability of appropriate simulation models taking account of the microscopic structure of such interesting composite is important for its design and performance optimization. In this letter, a novel simulation model is presented to carry out the microstructure design for improving radar absorbing performance of multineedle whisker RAM. First, this computational model is established according to equivalent medium theory and transmission line method. Then, calculative curve is compared to existing experimental data, and good agreement suggests that the proposed model can be a useful tool for microstructure optimization of this kind of RAM. Finally, the microstructures of a three-layer multineedle zinc oxide whisker (M-ZnOw) RAM are optimized by using the simulation model and particle swarm algorithm, and the numerical results demonstrate the potential of microstructure design for improving the radar absorbing property of such interesting composite.
