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

Figure 38

(a) Magnitude and (b) phase of in degrees for different resonator lengths and rotation angles. (c, d) Radiation patterns of (a) Dolph-Tschebyscheff and (b) uniform arrays. Both arrays redirect the normally incident plane wave at 33°. (e) Schematics of the top and bottom nanoapertures forming the super-unit-cell in the plasmonic metasurfaces for the demonstration of anomalous refraction. (f) The transmission phase and amplitude of each nanoaperture pair, calculated under -polarized incident light at 900 nm. (g) SEM image of the sample (left panel) and measured refraction angle (right panel). Figures are reproduced from [181, 210].
