本文提出了一种基于阻抗匹配零折射率超材料（ZIM）的高效任意角度弯曲结构。在波导系统中对ZIM弯曲进行了数值模拟。结果表明，电磁波可以在任意弯曲角度下以高透射率穿透ZIM基弯曲。此外，一个现实的ZIM基弯曲的微带传输线上的设计和制造。仿真和实验结果都很好地证实了采用ZIM微带环形谐振器作为弯角的系统的低损耗和任意角度的弯曲效果。
In this paper, efficient arbitrary angle bends based on impedance-matched zero-index metamaterials (ZIMs) are proposed. Numerical simulations on ZIM-based bends are carried out in waveguide systems. The results show clearly that electromagnetic waves can tunnel through the ZIM-based bends with high transmittance at any bending angles. Moreover, a realistic ZIM-based bends are designed and fabricated on microstrip transmission line. Both simulated and experimental results confirm well the low loss and arbitrary angle bending effects in a system hiring ZIM-based microstrip ring resonator as bending corners.
