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

Figure 42

(a) Schematic of the metamolecule of the active metasurface for polarization manipulation, and the transmission spectra are shown in (b). (c) Photography of the fabricated dipole antenna using tunable metasurface with its unit cell in (e), and the measured and AR of the designed dipole antenna for different working states are shown in (d) and (f). Figures are reproduced from [92].
