Figure 2

(a) Reflectance and transmittance spectra of the DGL resonance structure without SLG and (d) its electric field distribution; (b) reflectance, transmittance, and absorption spectra with SLG and (e) its electric field distribution; (c) phase spectrum of the reflection coefficient. Dotted lines in (d) and (e) indicate different layers of the DGL structure shown in Fig. 1 (black-dotted line: SLG). (d) and (e) are created by MathWorks MATLAB 2019b with in-house RCWA method.
