采用粒子群算法与微波仿真软件CST联合仿真的方法,针对拓展吸波带宽或降低吸波材料厚度的不同要求,通过设计不同的适应度函数,实现了对三维微带线阵列吸波结构材料的优化设计。设计结果表明,经过优化设计,吸波材料的吸波带宽可以增加30%,或在吸波性基本不变的条件下材料厚度减少15%。调节适应度函数中的权重,还可以有针对性地拓展吸波材料的频率低频段或高频段。所采用的计算流程可以全程自动进行优化处理。 Using the method of particle swarm optimization and CST co-simulation with microwave simulation software, aiming at the different requirements of expanding the absorption bandwidth or reducing the thickness of the absorbing material, the design of different fitness functions is carried out. Optimize design. The design results show that the optimized absorption bandwidth of the absorbing material can be increased by 30% or the material thickness can be reduced by 15% under the condition that the absorbing property is basically unchanged. Adjust the fitness function of the weight, but also can be targeted to expand the frequency of absorbing materials, low frequency band or high frequency. The calculation process used can be optimized automatically throughout the process.
