摘要

电磁波的极化特性在通信、导航和雷达等方面已逐渐得到应用.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 properties of electromagnetic wave have been gradually applied to the fields of communications, navigation and radar. In order to effectively control the polarization state of electromagnetic waves, a kind of metamaterial based on split-ring resonators(SRRs) is designed in this paper. The metamaterial is composed of SRRs, dielectric substrate and metal backplane, and it can completely convert incident linear-polarized waves into circular-polarized waves, elliptic-polarized waves and linear-polarized waves whose polarization is perpendicular to the incident wave. Our design is demonstrated by microwave experiments and simulations,and the experimental result and the simulation result are in good agreement with each other.
