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

Figure 49

(a) Optical images of a flexible metasurface when stretched. (b) Diffraction angle of the metasurface grating for different length of the PDMS substrate. (c) Schematic of a flexible color-filtering metasurface. (d) Measured reflectance spectrum when the substrate is uniformly stretched. (c, d) Figures are reproduced from [244].
