摘　　要：考虑到传统电磁优化仿真方法的低效性,在原始空间映射算法的基础上,构造一种有效的输入-输出空间映射算法,并用于优化设计一个微带带通滤波器,其替代模型和精确模型分别采用了基于电路原理的Agilent ADS和基于矩量法的全波电磁仿真软件FEKO进行计算分析。仿真结果表明,该算法能够有效增加所设计器件的优化自由度,大大减少计算机优化时间,有效提高了微波器件的设计效率。Considering the poor efficiency of traditional electromagnetism simulation and optimization methods, on the ba sis of the early space mapping algorithm, an effective input-output space mapping algorithm is constructed, which is used to optimized design a microstrip bandpass filter. The surrogate model and fine model are simulated in Agilent ADS and the full wave electromagnetism simulation software of FEKO separately. The simulation results indicate that the algorithm can in- crease the degree of freedom adequately for the optimizedcomponents, reduce the optimization time richly, and improve the design efficiency of microwave devices greatly.
