scientists try to introduce and develop new structures based on the plasmonics. In this paper we try to design and fabricate a new plasmonic polarizer based on metal nano-grating consist of silver thin film on polycarbonante gratings. Our results show the 28 % polarized light in overall visible light. This new devices can open a new insight in plasmonic based polarizers.

Keywords: Polarizer, metal gratings, plasmonic gratings, surface Plasmon polariton
