Novel reflection polarizers with double-layer subwavelength metal grating structure

Summary form only given. Control of the polarization of light is an important issue in many optical systems. Subwavelength gratings may provide the needed polarization functionality in a compact, low-cost format. However, the present study of subwavelength optical elements is very limited. In this study, we demonstrate a polarizing reflector with a double-layer subwavelength metal grating structure.
