Abstract
We explore the use of surface plasmon polariton (SPP) tomography far-field superlenses for quantitative characterization of plasmonic crystals with sub-wavelength features. Essential information concerning the dependence of the effective refractive index on the hole diameter and the filling factor was obtained from the Fourier-plane images of the fabricated plasmonic crystals. We also provide a comprehensive discussion on the influence of hole diameters on the formation of directional stop-bands in plasmonic crystals.
