我们提出了一个带型等离子体腔与银莫比乌斯带夹在介质层之间。通过简单的理论和模拟分析，我们得到了这种腔的因子保持在40左右，模体积非常小（小于1），比圆柱腔的模体积更加紧凑。这种支持表面等离子体激元传播的带状等离子体腔具有一些独特的性质，如更大的有效体积和空间分离。在未来的纳米光子学中，基于该腔的更多潜在应用仍有待探索。
We propose a Mobius-strip-type plasmonic cavity with a silver Mobius strip sandwiched between dielectric layers. By brief theoretical and simulation analyses, we obtain that the factor of the cavity remains about 40 and the mode volume is ultrasmall (less than 1 ) which is more compact than that of the cylindric cavity. This Mobius-strip-type plasmonic cavity supporting the propagation of surface plasmon polaritons owns some unusual properties such as more effective volume and the spatial separation. More potential applications based on this cavity remain to be explored in future nanophotonics.
