Effect of Unit Cell Shape on Switchable Infrared Metamaterial VO2 Absorbers/Emitters

Figure 1

Four switchable infrared metamaterial emitters and their “switching on/off” ability of absorption. (a)–(f) Schematic of four switchable infrared metamaterial emitters consists of Ag/VO2/Ag. (g)–(j) The spectral absorptance of emitters employing triangular, square, hexagonal, and circular structures, within 2.5-7 μm when VO2 is in insulating (blue lines) and metallic (red lines).
