摘要
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0.8～6GHz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.
