| 摘 要： | 从基本的电磁波传播理论出发,利用已有的多层平板复合电磁屏蔽材料的理论模型,将遗传算法应用到屏蔽材料的设计中。通过该算法,可以设计出在指定屏蔽效能、不同入射角度的电磁波和指定的频带要求下的各层屏蔽材料。最后对该算法进行了仿真,仿真结果表明该方法是切实有效的,从而为设计多层屏蔽材料提供了一种简便有效的方法。

| Abstract: | Based on the basic propagation theory, the genetic algorithm is used in the design of the multilayered composite materials by means of the existing multilayered planar composite electromagnetic shielding materials model. With this method, different shielding materials of every layer can be achieved under the circumstances of the prespecified shielding effectiveness (SE), different incident angles and the prespecified band of frequencies. Finally the method is simulated, the result has demonstrated the validity of the method, thus providing an effective method for the design of the multilayered composite shielding materials. |
