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.
