摘　　要：针对传统等效电路法在分析复杂频率选择表面(FSS)电磁特性时精度不够的问题,提出了基于强化学习和全波分析的FSS等效电路建模方法。分别以六边形孔径FSS以及含介质加载的双层级联FSS为例,给出了等效电路建模方法,并通过与传统等效电路法、全波仿真分析结果的对比验证了该方法的有效性。仿真结果表明:基于强化学习和全波分析的FSS等效电路建模方法能够准确高效地分析复杂FSS的电磁特性。Aiming at insufficient accuracy of the traditional method in designing the frequency selective surface(FSS),a new composite method based on the reinforcement learning and full wave simulation was proposed.Hexagonal aperture FSS and the twolayer cascaded dielectric FSS were built and analyzed with this method.The result was verified by comparing with the traditional method and full wave simulation results.The results show that our proposed method can analyze the electromagnetic characteristics of complex FSS efficiently and accurately.
