现有的粒子群优化算法(PSO)在传统多层平板吸波材料的优化过程中收敛速度慢,寻优精度低.为了改善设计的收敛速度和寻优精度,利用改进简化粒子群优化方法(ISPSO)在传输线法计算模型基础上对多层吸波材料进行了优化设计.优化设计结果表明,在0.8~6 GHz范围内,5层吸波材料的反射系数在-22.98 dB以下,得到的结果比现有文献好.

In the optimization of traditional multi-layer absorbing materials,the existing Particle Swarm Opti-mization(PSO)algorithms have slow convergence and low accuracy. In order to improve the convergence speed and optimization accuracy,based on the multi-layer absorber computational model of the transmission line method,an improved simplified particle swarm optimization method(ISPSO)is applied to optimize the multi-lay-er absorbing materials. The simulation results show that the reflection coefficient is below -22.98 dB within 0.8~6 GHz. Compared with the original literature,the optimal results are excellent.
