Fig. 4. (Color online) Incident-angle-dependent (a) reflection and (b) transmission spectra for TDBC thin films with a thickness of 50 nm. Same for TDBC thin films with thicknesses of (c,d) 100 nm and (e,f) 200 nm. The light blue shadowed area represents the metallic region with the negative real part of permittivity.
