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

Figure 55

(a) Dispersion of an ultrathin metallic film with ultrasmall effective wavelength. (b) Dispersion of a metasurface consisting of metal-insulator-metal (MIM) structure, which acts as a high efficient color filter. (c) Lorentz dispersion for broadband metasurface absorber. (d) Lorentz-type dispersion for broadband polarization control. Figures are reproduced from (a) [55], (b) [17], (c) [114], and (d) [81].
