提出了一种由平面电路型谐振器组成的紧凑、无辐射、易于制作的左波导材料。结果表明，te型倏逝场与e-负材料中的场等效，谐振腔作为负磁导率的粒子工作。左手模的存在性由场分布和色散关系来保证。在表明这两种成分对材料的介电常数或磁导率有影响之后，基于阻抗的概念，将材料与传统波导匹配。最后将该材料应用于左手漏波天线。
A compact, nonradiative, and easy fabricated left-handed material composed of planar circuit-type resonators in a cutoff waveguide is proposed. It is shown that the TE-type evanescent field is equivalent to the field in e-negative material and the resonator works as a particle with negative permeability. The existence of a left-handed mode is ensured by a field distribution and a dispersion relation. After showing that the two constituents have an influence on the permittivity or the permeability of the material, on the basis of an idea of impedance, the material is matched to a conventional waveguide. Finally the material can be applied to a left-handed leaky-wave antenna.
