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

Figure 12

Schematic configuration of the (a) triple-band circular polarizer, (c) four-band chiral metasurface, and (e) dual-band circularly polarized horn antenna based on chiral metasurface. (b, d) Simulated and measured circular transmission for the chiral metasurface of (a) and (c). (f) Radiation patterns in LCP and RCP of the antenna at 14.35 GHz. Figures are reproduced from [86, 89, 90].
