spoof surface plasmonssurface plasmonsLocalized surface plasmons (LSPs) are localized oscillations of free electrons in metal nanoparticles at optical frequencies. Confined mode profiles and near‐field enhancements make LSPs ultrasensitive to the dielectric environment, making them good candidates as sensors....
Surface plasmons exist either as propagating surface plasmon polaritons (SPPs) at the extended interface of metal and dielectric or as localized surface plasmons (LSPs) on small metal particles3. LSPs have been of interest for increasing applications in the optical antenna4,5, surface-enhanced Raman...
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. The HCGs are in the form of a periodic array of radial dielectric...
The laminated ferroelectric compound resonator is composed of a ferroelectric Ba0.85Ca0.15Zr0.9Ti0.1O3 (BCZT) layer, a PCB layer, as well as a localized spoof plasmonic metal layer, where the BCZT layer is beneficial for enhancing the voltage tunability in the spoof surface pla...

The modes in the structure arise from the coupling of conventional parallel plate waveguide modes with the localized modes of the grooves. SIS waveguides can be engineered to guide modes with low group velocities and SIS tapers can be used to convert light between photonic modes and plasmonic ...

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 ...
