| 摘 要： | 根据传输矩阵法和递推法导出了多层吸波体的反射率公式.利用遗传算法对吸波体各层参数进行了优化设计.分别仿真了右右手材料双层吸波体,右左手材料双层吸波体,左右手材料双层吸波体,左左手材料双层吸波体的反射率随频率的变化曲线.研究结果表明,右左手双层吸波体的性能最好.左手材料作为损耗层时反射率随频率的变化曲线出现多峰现象,有利于频带的展宽.

| Abstract: | The reflectivity of the double-layer absorber is calculated according to the transmit matrix and recursion method.The parameters of each layer are optimized applying Genetic Algorithm.The absorption ability of four kinds of absorber which are made with RHMs-RHMs,LHMs-RHMs,RHMs-LHMs,LHMs-LHMs is stimulated respectively.The research result shows that the absorption ability of the absorber with RHMs-LHMs is the best.When the second layer is made with the LHMs,the absorber possesses the multi absorption peaks,w... |
