Taming the Electromagnetic Boundaries via Metasurfaces: From Theory and Fabrication to Functional Devices

Figure 25

(a) Schematic representation of subradiant () and superradiant () modes. (b) Scanning electron microscopy image of a typical fabricated sample. (c) Schematic representations of proteins’ mono- and bilayers binding to the metal surface. (d) Experimental (solid) and theoretical (dashed) polarized reflectivity spectra. (e) SEM image of a fabricated metasurface consisting of hole array. (f) Resonance shift for the subradiant SPP mode with changing NaCl concentration. Figures are reproduced from (a)–(d) [144] and (e, f) [148].
