Abstract As a popular artificial composite material emerging in recent years, metasurfaces are one of the most likely devices to break through volume limitation conventional optical components due their compact structure, flexible materials, and high modulation resolution beam. With unique arrangement units or made special metasurface can effectively modulate incident light's amplitude, phase, polarization, frequency, thus realizing applications such as communication, imaging, sensing, beam steering. The interaction high‐resolution periodic arrangement, constituent materials makes it possible realize these applications, so researchers should choose appropriate micro‐nano processing technologies when designing preparing metasurface. This review will present related preparation metasurfaces, electron lithography (EBL), femtosecond laser processing, focused ion (FIB), additive manufacturing, nanoimprinting, self‐assembly, respectively. In addition, classical techniques wet lithography, plasma deep reactive etching (DRIE), photolithography be introduced. Their development history functions described detail, examples micro‐nano‐structures different branches presented, well some using techniques. this paper has produced several tables describing technologies, outlining resolution, advantages disadvantages, on. Hopefully, provide with options ideas for metasurfaces.

Abstract The thermal phase transition characteristics of vanadium dioxide can effectively regulate the absorption performance metamaterial absorbers. A petal‐shaped absorber is designed based on control and prepared samples using surface projection micro stereolithography (PµSL) 3D printing technology. Then, thin films are coated ultrasonic spraying method. PµSL technology makes it possible to prepare high‐precision complex samples, method enables coating at room temperature. To demonstrate stability this method, two different structures prepared: planar structure hemispherical structure. In experiment, a non‐contact heating used temperature film, which made sample controllable, stable, uniformly heated. experimental results show that has excellent modulation switching characteristics, proves reliability
