The spoof localized surface plasmon (LSP) resonance modes can be excited by the interaction between plasmonic waveguide and CDR. Fundamental and higher order sharp spoof LSP resonances (from dipole to dodecapole) were observed in the transmission coefficient spectrum. The Q-value as high as 268.3 ...
Jia Xu1, Chen Chen1, Changqing Gu1 & Yongjin Zhou5 In this work, we report the existence of spoof localized surface plasmons (spoof-LSPs) arising with closed high contrast gratings (HCGs) at deep subwavelength scales, another platform for field localization at microwave frequencies. Th...
15 April 2016 High-order spoof localized surface plasmons supported on a complementary metallic spiral structure Zhen Gao1, Fei Gao1 & Baile Zhang1,2 We experimentally demonstrate that multiple high-order spoof localized surface plasmons (spoof- LSPs) modes can be supported on a complem...

We theoretically demonstrated and experimentally verified high-order radial spoof localized surface plasmon resonances supported by textured metal particles. Through an effective medium theory and exact numerical simulations, we show the emergence of these geometrically-originated electromagnetic modes at microwav...
This paper proposes a theory based on the interaction between spoof surface plasmon polaritons (SSPPs) and spoof localized surface plasmon (SLSPs) for the purpose of detecting moisture content in wood utilizing a planar terahertz sensor structure. The numerous resonance frequencies generated by this ...
Interestingly, we find that the localized spoof surface plasmon polariton has a significant toroidal dipole moment, which is responsible for the high Q factor, as well as an electric quadrupole moment. In addition, the dispersion properties of spoof surface plasmon polaritons are analyzed using a ...

We report on the first observation of ‘Spoof’ Surface Plasmon Polariton (SPP) scattering from surface defects on metal-coated 3D printed, corrugated THz waveguiding surfaces. Surface defects, a result of the printing process, are shown to assist the direct coupling of the incident free-space ra...
