The original paper contains errors in Figs. 2(b) and 3 regarding the contribution to the transmission of different resonant states and the cuts, whereas the total transmission is correct. Also, Fig. 2(b) of the original paper includes the leaky-mode (LM) and the antiwaveguide(AWG-) mode components, suggesting that they contribute to the total transmission in the frequency domain. However, these modes are on a different Riemann sheet of complex frequency ω as compared to the waveguide (WG) and Fabry-Pérot (FP) modes. In the calculation of the transmission, one can choose any of the two Riemann sheets where the analytic continuation of the transmission t(ω) is defined. We choose the Riemann sheet containing the WG and FP modes and show in Fig. 2(b) their contributions along with the component due to the cuts which are displayed in Fig. 1 of the original paper.
