本文提出了一种左右手复合圆柱形波导。在中空波导中通过截止TM01模实现负磁导率，在带脊扇形波导中通过截止主导TE模实现负介电常数。通过对有限元单元结构的色散图和传输特性的数值计算，验证了所提出的圆柱形波导的有效性。最后，对制作的光波导进行了测量，并进行了实验验证。
This paper proposes a composite right/left-handed cylindrical waveguide. Negative permeability is realized by the cutoff TM01-mode in a hollow waveguide, and negative permittivity is realized by the cutoff dominant TE-mode in a sector waveguide with a ridge. Usefulness of the proposed cylindrical waveguide is verified from the numerical computations of both the dispersion diagrams and the transmission characteristics of the structure with finite-number unit cells. Finally, measurement of the fabricated waveguides is performed for the experimental verification.
