We show that negative resonant modes with an inverse relationship between the wavelength and the cavity length can be excited in a hyperbolic metamaterial slot cavity (HMMSC) in addition to positive resonant modes. The observed negative resonant modes in an HMMSC are in sharp contrast to that observed in a metal slot cavity. We analyze the dynamics of the excited negative resonant modes in the visible spectrum regime as HMMSC parameters vary.

双曲超材料缝隙腔中的负共振模式

我们表明，除了正共振模式外，在双曲超材料槽腔（HMMSC）中还可以激发波长与腔长度之间具有反比关系的负共振模式。在HMMSC中观察到的负共振模式与在金属槽腔中观察到的共振模式形成鲜明对比。当HMMSC参数变化时，我们分析了在可见光谱范围内激发的负共振模式的动力学。
