首次证明了利用非倒易超材料线对伪行波谐振腔的场分布进行二自由度控制。基于电路理论，给出了谐振腔电流分布的动态控制。我们采用常磁铁氧体微带线复合左/右（CRLH）传输线作为可变相移非互易的超材料。数值模拟结果表明，沿谐振腔场的相位梯度由施加在铁氧体上的直流磁场控制。通过改变插入CRLH线段两端的两个反射器的反射系数，在谐振作用下，电流沿单元胞串联分支和分流分支的分布发生连续而剧烈的变化。对极化-平面旋转和波束扫描漏波天线进行了变场分布。实验验证了我们的基本概念，并展示了在固定频率下波束扫描角为20°，偏振面连续旋转角度为±70°的原型天线的性能。
Two-degree-of-freedom control of field distribution on the pseudotraveling wave resonator using nonreciprocal metamaterial lines is demonstrated for the first time. Dynamic control of current distribution on the resonator is given based on circuit theory. We employed a normally magnetized ferrite microstrip line-based composite right-/left-handed (CRLH) transmission line as a metamaterial with variable phase-shifting nonreciprocity. Numerical simulation results show that the phase gradient of the fields along the resonator is controlled by the applied dc magnetic field to the ferrite. By changing the reflection coefficients of two reflectors inserted at both ends of the CRLH line section, current distribution along series and shunt branches of the unit cell is continuously and drastically changed under the resonance. The variable field distribution was implemented to polarization-plane-rotation and beam-scanning leaky-wave antennas. The experimental demonstration verifies our basic concept and shows the performance of the prototype antenna with a beam scanning angle of 20° and a continuous rotation angle of polarization plane by ±70° at the fixed frequency.
