Surface Plasmon Resonance in Periodic Hexagonal Lattice Arrays of Silver Nanodisks
Figure 3
(a) The transmission spectra of periodic arrays with different diameters between 20 nm and 150 nm. (b) -field enhancement factor of periodic arrays with different diameters illuminated at three laser light wavelengths (488 nm, 532 nm, 632.8 nm). The gap between the nanodisks is fixed at 70 nm.
