我们证明了具有多个凹槽深度的周期性织构闭合表面可以支持多带欺骗局域表面等离子体(LSP)。有趣的是，每个带中的欺骗LSP类似于由具有相应单槽深度的相同周期的纹理闭合表面产生的欺骗LSP。从而为多频段欺骗LSP的产生和设计铺平了道路。此外，还可以实现微波和太赫兹区的多个谐振带结构和器件，如谐振器、振荡器和其他带阻结构。
We demonstrate that periodically textured closed surface with multiple groove depths can support multi-band spoof localized surface plasmons (LSPs). It is interesting to note that the spoof LSPs in each band resemble those generated by the textured closed surface of the same periodicity with the corresponding single groove depth. In this way, it paves the way for the generation and design of multi-band spoof LSPs. Moreover, multiple resonance band structures and devices, such as resonator, oscillator, and other band-notched structures in the microwave and terahertz regimes can be realized.
