(a) Schematics of the multilayered plasmonic crystals; blue arrows show incident light configuration. (b) SEM image of a periodic array ( and ).
(a) field patterns of , , and are shown, respectively, from top to down. (b) The absolute transmission spectra of the structures for crystals with diameter and varying periodicities from 550 to 400 nm with 50 nm steps, respectively, from top to down.
Cross sectional field patterns are shown for (a) , (b) , (c) , and (d) FP peaks. Cross sections are obtained at resonance peaks (, , , and , respectively) using a Fourier transform. Simulation is done with a structure of 300 nm diameter and 400 nm periodicity.
Comparison of spectrum (a) with changing dielectric layer thickness, (b) with changing diameter, and (c) with changing periodicity. (d) Shifts in spectral position with changing RI for FP peak (red) and peak (blue).
