Abstract
A flat Nano-metallic (Silver) surface plasmonic lens for wider optical wavelength operation based on the phase and amplitude modulation by tuning the slit widths is introduced. The design novelty lies on its complex structure with the macro-parameters such as focal length with freedoms in its material profile, thickness, slit width and the pitch. A simplified implementation of the Nano-metallic lens with equidistant slits but bearing different widths is evaluated using the finite difference time domain method. The design tolerance and variation in the focal point position in accordance to alteration in the properties of the lens are explored in brief.
