Stretchable Metasurfaces: Mechanical Terahertz Modulation by Skin‐Like Ultrathin Stretchable Metasurface (Small 37/2020)

Here, a free‐standing, skin‐like and highly stretchable metasurface with the mechanical modulation of the terahertz transmission is illustrated. In article number 2002484, Yuhang Li, Taisong Pan, and co‐workers fabricate the stretchable metasurface by merely constructing an Al/PI mesh film consisting of serpentine‐like unit cells, only with a total thickness of 7 μm. The metasurface shows the band‐stop frequency selective effect because of the periodic Al/PI mesh composition. With the novel mechanical design, the metasurface can be stretched, bent and twisted, which provides the possibility to modulate terahertz transmission properties by the mechanical deformation.
