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

Figure 36

Far-field superresolution based on metasurface. (a) Schematic of the experimental setup. The inset shows the phase distribution of the metasurface. Gray regions and white regions indicate 0 and , respectively. (b) Experimental results for a circular hole at wavelength of = 532 nm. (c) Simulation results for a triangular hole. Figures are reproduced from [2].
