中文摘要：
利用遗传算法对超材料进行优化设计，是近年来超材料优化设计的重要方法之一。设计了一套MATLAB与商业电磁仿真软件CST微波实验室的交互仿真体系，在MATLAB环境中编写遗传算法主程序，然后离线调用CST软件进行模型仿真计算，从而将具有强大全局寻优能力的遗传算法充分应用到超材料的优化设计中。然后以 Y字紧凑型结构的二阶带通频率选择表面优化设计为例，采用基于罚函数法的遗传算法对这种设计思路进行了验证，取得了良好的设计效果。结果表明：与以往的设计方法相比，该方法编程简单，通用性强，设计周期短，优化效果好，同时可以推广到其他类型的超材料结构的优化设计中。
英文摘要：
Optimization of meta-materials with the genetic algorithm is one of the most effective methods in the design of meta-materials in recent years.An integral system with interactive simulation of MATLAB and CST Microwave Studio is developed,and the main program of genetic algorithm is written in MAT-LAB with simulation and computation in CST to realize optimization of meta-materials by genetic algo-rithm with power of global optimization.Taking the compact second-order frequency selective surface opti-mization for example,the thinking of design is verified based on penalty function genetic algorithm,and a good effectiveness is obtained.Compared to the previous realizing way,this method is simple in program-ming operation,better in generality,and only needs a short circle design,simultaneously the method can be applied to other kinds of meta-materials.
