  • 设计任意调控极化的电磁器件是一个研究热点, 其中多功能可重构电磁器件在雷达、卫星通信等领域有着广泛的应用. 本文设计了一种基于正本征负极(PIN)二极管可调谐的多功能可重构极化转换超表面, 可以实现不同频段内的线极化波转换、线极化波-圆极化波转换和全反射功能的切换, 在斜入射角小于30°时, 多功能转换器能保持高效的宽带极化转换特性. 这种转换和重构特性主要是由于结构本身的各向异性和PIN管不同状态时耦合模式的改变. 此外, 利用表面电流解释了偏振转换的物理机理, 电谐振和磁谐振的共同作用导致了偏振转换. 最后, 对该结构样品进行实验验证, 其结果与仿真吻合较好. 该器件在极化调控、频率控制、智能反射面设计和天线设计等方面具有潜在的应用价值.
    The design of electromagnetic device with arbitrary polarization manipulation is the hot spot of the current research. Multifunctional reconfigurable electromagnetic devices have been put into wide applications in radar, satellite communication and other fields. In this work designed is a multifunctional reconfigurable polarization conversion metasurface based on two PIN diodes, which can realize linear polarization conversion, linear-circular polarization conversion and total reflection switching in the different frequency bands, and the multi-function converter can still maintain the high-efficient broadband conversion characteristics when the oblique incidence angle is less than 30 degrees. The polarization conversion and reconfigurability are mainly due to the anisotropy of the structure and the changes of coupling mode in different states of PIN diodes. In addition, the physical mechanism of polarization conversion is explained by surface current. The combined action of electric resonance and magnetic resonance results in polarization conversion. Finally, the experimental results of the sample are in good agreement with the simulation results. The device has the potential application values in polarization manipulation, frequency control, intelligent reflecting surface design, and antenna design and so on.
