Abstract :
We design, fabricate and characterize periodic arrays of X-shaped nano-aperture antennas in Ag and Au films. By matching the plasmonic resonance of individual antennas to that of the lattice arrangement, we demonstrate increased optical transmission and field concentration leading to enhanced Raman scattering.
