In this project, we proposed a meta-material based stub resonator utilizing negative-order resonance mode, with compact size and frequency tunability. The compact resonator sizes less than 1/3 of conventional half-wavelength stub resonators. We demonstrate that the slow group velocity of the left-handed waves enhances the unloaded-Q of the resonator by a factor of 2 or more. As a result, the loaded-Q, controlled by the left-handed reactive elements, can be arbitrarily increased without incurring significant insertion loss as in the case of conventional right-handed stub resonators. The physical mechanism of the distinct features is discussed based on measured and simulated results.

在本计画中，我们提出一种利用负阶共振模式的超材料短截线共振器，具有体积小、频率可调等优点。紧凑的谐振器的尺寸小于传统的半波长短截线谐振器的1/3。我们证明了左手波的慢群速度增强了谐振器的空载Q值的2倍或更多。结果，由左手电抗元件控制的加载Q可以任意增加，而不会像传统右手短截线谐振器的情况那样引起显著的插入损耗。根据实测和模拟结果，讨论了这些特征的物理机制。
