摘要

本文提出了一种近场聚焦圆柱全息阻抗超表面的设计方法。首先，基于平面全息阻抗超表面的设计理论，采用长轴匹配的方法推导出圆柱全息阻抗超表面的设计公式;然后通过仿真和实测验证了理论分析的可行性。结果表明，该设计方法能有效地实现近场聚焦，可为微波热疗和能量收集等保形装置的应用提供参考。

DESIGN OF CYLINDRICAL HOLOGRAPHIC IMPEDANCE METASURFACE FOR NEAR-FIELD FOCUSING

—In this paper, a design method for near-ﬁeld focusing cylindrical holographic impedance metasurfaces is proposed. Firstly, based on the design theory of planar holographic impedance metasurface, we deduce the design formula for cylindrical holographic impedance metasurface by using the method of major axis matching. Then the feasibility of theoretical analysis is veriﬁed by simulation and measurement. The results show that the design method can eﬀectively realize the near-ﬁeld focusing, which can provide a reference for the application of conformal devices for microwave hyperthermia and energy harvesting.
