We investigated the design, optimization, and evaluation method of an infrared (IR)/microwave (MW) multilayered dielectric plate type of beam combiner. The MW multilayered dielectrics design theory and IR film design theory were unified using transmission line theory. The principles in designing the initial structure of a beam combiner were presented. An objective function was presented in optimizing the beam combiner. Six evaluation indices were constructed to evaluate the performance of the beam combiner. To verify the feasibility of the proposed method an example was given. The results showed that the method could meet the joint design, optimization, and evaluation requirements of a beam combiner's IR and MW characteristics. Finally, the design, optimization, and evaluation procedure was summarized.
我们研究了一种红外（IR）/微波（MW）多层介质板型光束组合器的设计、优化和评估方法。利用传输线理论将微波多层介质设计理论与红外薄膜设计理论统一起来。提出了光束组合器初始结构的设计原则。给出了优化光束组合器的目标函数。构建了六个评估指标来评估光束组合器的性能。为验证所提方法的可行性给出了一个实例。结果表明，该方法能够满足光束组合器红外和微波特性的联合设计、优化及评估要求。最后，总结了设计、优化和评估过程。
