本文提出了一种周期性填充铁氧体的矩形波导作为一种新型的左旋传输线。表面波模可以在截止频率以下周期性填充铁氧体片的矩形波导中传播。发现了波在LH传输线中传播的新机制，即它显示了沿波导的消失模链行为。该传输线可用于紧凑型铁氧体移相器和谐振器。
In this paper, a rectangular waveguide periodically filled with ferrite is proposed as a new type of LH transmission line. The surface wave mode can propagate in the rectangular waveguide periodically filled with ferrite slabs at frequencies below the cut-off. The new mechanism of wave propagation in the LH transmission line was found that it shows the chain behavior of evanescent modes along the waveguide. The LH transmission line proposed in the paper may be useful for applications to compact ferrite phase shifters and resonators.
