PROJECT TITLE :
Comparison of Refractive-Index Sensitivities of Optical-Mode Resonances on a Finite Comb-Like Grating of Silver Nanostrips
We tend to investigate the interplay of several completely different varieties of resonances in the scattering of sunshine by finite comb-like nanogratings made of silver strips, within the H- and E-polarization cases. The resonances studied correspond to the localized surface plasmon modes, the periodicity-induced grating mode, and also the cavity modes. They show up as Fano shapes in the entire scattering cross sections and absorption cross sections. We have a tendency to notice that the grating-mode and the cavity-mode resonances have higher values of each bulk refractive-index sensitivity and figure-of-advantage than the localized-surface-plasmon resonances, in the visible band.
