A variable birefringence effect has been observed with 1D PMMA surface gratings on a gold film substrate. By changing the operation wavelength on the Au film, the birefringence value Δn(eff) changes from positive to negative. The result verified that this uniaxial crystal-like plasmonic surface gratings showed good superlensing effect at 515 nm when PMMA width:Air width=1:1 where the absolute value of Δn(eff) is relatively large.
