摘要

设计了一种工作频率为60 GHz的平面、聚焦、超材料透镜，该透镜采用由金属棒和开环换向器组成的三层元件。其自由空间焦距为15毫米。我们还模拟了一个系统，其中一对这样的透镜放置在由两层皮肤-血液结构组成的生物组织的两侧。当被贴片天线激发时，指向性提高9.5 dB。

Design of a subwavelength flat focusing lens and simulation of its performance in the presence of biological tissues at millimetre waves

A flat, focusing, metamaterial lens, operating at 60 GHz was designed using 3-layer elements consisting of metallic bars and split ring commutators. Its free space focal length is 15 mm. We also simulated a system where a pair of such lenses is placed on either side of biological tissue consisting of a 2-layer skin-blood structure. When excited by a patch antenna, the directivity is enhanced by 9.5 dB.
