(a) The reflection (Rss), transmission (Tss) and polarization transformation (Rsp and Tsp) intensities of TE0-BSW versus the angle of incidence. (b) The reflection (Rpp), transmission (Tpp) and polarization transformation (Rps and Tps) intensities of TM1-BSW versus the angle of incidence. The signs with triangle and circle denote the results obtained from FDFD method. In simulation, the top layer’s thickness h = 320 nm, the width wg and depth hg of the groove are 400 nm and 150 nm, respectively. The intensities of Rsp, Tsp, Rps and Tps are magnified by a factor of 10. The incident wavelength of the light in vacuum is 633 nm.
