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