Abstract

Two planar dielectric reflectors with polarization-independent focusing ability have been designed. They are designed and compared on the base of the square lattice of circular two-dimensional (2-D) subwavelength gratings (SWGs) and the hexagonal lattice of circular 2-D SWGs on a silicon-on-insulator wafer.
