FIG. 7.
(a) Polarization transformation intensity Rsp and (b) the reflection intensity Rss of TE0-BSW versus the incidence angle and the separation distance Ld between grooves. The incidence angle of TE0-BSW is fixed at 50.6°. The electric field intensity distributions for different separation distance (c) Ld = 410 nm, (d) Ld = 680 nm. The wavelength of the incident light in vacuum is 633 nm.
