摘要

提出了一种基于元素群的单层超表面，它由两个相似的单元组成。该元件组可以覆盖360°以上的相移范围，传输效率超过- 3db。此外，还为医疗应用构建了一个工作在11GHz的超表面聚焦透镜。仿真结果表明，电磁功率可以集中在近场的一个点上。

Single-Layer Metasurface Focusing Lens for Medical Applications

A single-layer metasurface based on the element-group which consists of two similar unit cells is proposed in this paper. The element-group can cover the phase shift range of more than 360° with transmission efficiencies over −3 dB. Also a metasurface focusing lens working at 11GHz is built for medical applications. The presented simulation results show that the electromagnetic power can be focused on a spot in the near-field.
