摘要
研究了遗传算法在复合型阻抗加载微波吸收材料设计中的应用,分别对多层铁氧体吸波材料和复合型阻抗加载吸波材料的厚度和结构进行了优化计算。理论分析结果表明,随着阻抗加载电路在多层铁氧体吸波材料中的加入,3 mm厚和5 mm厚的吸波材料的吸收性能分别提高了20%和10%,而且在频段上也更加符合宽须吸收的要求。
This paper presents the optimum design for the composite impedance loaded microwave absorbing materials using the genetic algorithm (GA). The thickness and the structure of the multi-layer ferrite absorbing materials and the composite impedance loaded absorbing materials are optimized. The results show that the absorbing performances of the 3-mm-thick and 5-ram-thick microwave absorbing materials increase by 20 % and 10 % respectively with the use of the composite impedance loaded materials. A wider microwave absorbing frequency band is obtained.
