摘要

针对太赫兹频率区域的应用，提出了一种宽带轻型极化转换器。所提出的设计具有元表面结构，介电层被修改为空心结构，以获得轻质设计。单元单元由两个相对的弧形谐振器贴片和一个被聚酰亚胺基底层隔开的连续金属贴片组成。模拟结果表明，在 1.6 太赫兹至 5.8 太赫兹的频率范围内，拟议的极化转换器实现了 93% 以上的极化转换率，相对带宽为 113.5%。

A SIMPLE DESIGN OF BROADBAND CROSS-POLARIZATION CONVERTER FOR THE THz FREQUENCY RANGE

A broadband and lightweight polarization converter is proposed for applications in the THz frequency region. The proposed design has a metasurface structure with the dielectric layer modified to a hollow structure to obtain a lightweight design. The unit cell consists of two opposite arcs resonator patches and a continuous metal patch separated by the polyimide substrate layer. The simulated results indicate that the proposed polarized converter achieves a polarization conversion ratio above 93% in the frequency range from 1.6 THz to 5.8 THz with a relative bandwidth of 113.5%.
