基于非线性优化方法研究了圆环单元频率选择表面（ＦＳＳｗ ｉｔｈ Ｃｉｒｃｕｌａｒ Ｒｉｎｇ ＵｎｉｔＣｅｌｌｓ）的设计问题，文中提出了圆环单元ＦＳＳ的新设计模型，探讨了该模型的计算方法．该模型可同时对影响ＦＳＳ频率特性的所有因素进行优化，并具有计算时间短、占用内存少的特点．仿真模拟结果表明，所提出的新模型及其计算方法可靠有效．

Based on the nonlinear optimization method, the design of the frequency selective surfaces (FSS) with ring unit cells has been discussed. A novel design model for the FSS is proposed, and its computation method is presented. Numerical results show that the new model and its computation method are very effective, rather simple and easy to handle.
