Figure 2. The designing and simulation results of two PBSs.

(a, c, e, g) The designing and simulation results of the first PBS: (a) The first PBS is only composed of “period 1”. (c) The phase-delayed distributions of three periods along x direction for both x- and y-polarized reflected waves (Φ_1x(x) and Φ_1y(x)), in which solid black line and dashed blue line are calculation results and discrete pentacles and dots are simulation results of actual structures. (e) The electric-field distributions of x-polarized reflected waves deflected to (ϕ_1x = 180°, θ_1x = 30°). (g) The electric-field distributions of y-polarized reflected waves deflected to (ϕ_1y = 0, θ_1y = 30°). (b, d, f, h) The designing and simulation results of the second PBS: (b) The second PBS is composed of both “period 1” and “period 2”. (d) The phase-delayed distributions of three periods of “period 1” along x direction for y-polarized reflected waves (Φ_2y(x)) and three periods of “period 2” along y direction for x-polarized reflected waves (Φ_2x(y)), in which solid black line and dashed blue line are calculation results and discrete pentacles and dots are simulation results of actual structures. (e) The electric-field distributions of x-polarized reflected waves deflected to (ϕ_2x = 270°, θ_2x = 30°). (g) The electric-field distributions of y-polarized reflected waves deflected to (ϕ_2y = 0, θ_2y = 30°).
