首次提出并研究了一种铁氧体左手传输线，它由周期性加载电容和电感的铁氧体微带线构成。当左手传输的通带与负导磁率频率区重叠时，在边缘导模的正导磁率频率区和负导磁率频率区，用有限元法数值计算得到了隔离度大于20 dB的非互易传输特性，并进行了实验验证。
A ferrite left-handed transmission line has been proposed and investigated for the first time, which is composed of a ferrite microstrip line loaded periodically with capacitances and inductances. The nonreciprocal transmission characteristics with the isolation of greater than 20 dB are numerically obtained by finite element method and demonstrated experimentally in the positive and negative permeability frequency region for edge guided modes when the passband in the left-handed transmission overlaps with the negative permeability frequency region.
