Optimal filling factor of nanorod lenses for subwavelength imaging

Kosulnikov, Sergey Y; Yankovskaya, Elizaveta A; Maslovski, Stanislav I.; Belov, Pavel A; Kivshar, Yuri


We analyze the effect of the filling factor on the imaging performance of metallic nanorod lenses. We observe that thicker nanorods allow lower reflection in the canalization regime and we find optimal values of the filling factor to achieve a transfer function with the characteristics of a perfect lens in a wide range of spatial frequencies.
