电磁波的极化特性在通信、导航和雷达等方面己逐渐得到应用.为了有效控制电磁波的极化状态,本文设计了一种基于开口环结构的人工异向介质.该人工异向介质由开口环结构,电介质基底和金属背板组成,可以将入射的线性极化波完整地转换为圆极化波,椭圆极化波以及和入射波极化方向垂直的线极化波.本文通过实验和仿真验证了本文的设计,实验结果和仿真结果符合较好.
The polarization characteristics of electromagnetic waves have been gradually applied in the fields of communication, navigation and radar.In order to effectively control the polarization state of electromagnetic waves, an artificial anisotropic medium based on open-loop structure is designed in this paper.The artificial anisotropic medium consists of split ring Structure, dielectric substrate and metal backplane, the incident linearly polarized wave can be completely converted into a circularly polarized wave, an elliptically polarized wave and a linearly polarized wave perpendicular to the direction of polarization of the incident wave.Through experiments and simulations Verify the design of this paper, the experimental results and simulation results are in good agreement.
