Transmission spectrum of 1D APTSPROWN corresponding to different values of nb near WBP-1 when na = 1.700. Blue, purple, black, and red lines represent the results that the values of nb are 8× 10−6, 4.21× 10−8, 4.21× 10−10, and 4.21× 10−2, respectively. (a) Overall spectrum and (b) zoomed part of spectrum.
