Extraordinary propagation characteristics of electromagnetic waves in one-dimensional anti-PT-symmetric ring optical waveguide network
Transmission spectrum of 1D APTSPROWN corresponding to different values of nb near SBP-1 when na = 1.700. Blue, purple, black, and red lines represent results that values of nb are 3.24× 10−7, 3.24× 10−8, 3.24× 10−9, and 3.24× 10−3, respectively. (a) Overall spectrum and (b) zoomed part of spectrum.
