From: A new class of transformable kirigami metamaterials for reconfigurable electromagnetic systems
(a) FSS specimens. (b) Experiment setup. Measured and simulated transmittances of the triangle kirigami FSS in its closed and fully open configurations to a (c) horizontally and (d) vertically polarized incident wave. (e) Measured and simulated transmittance of the star kirigami FSS in its closed and fully open configurations. (f) Simulation of the switchable on–off FSS obtained by modifying the star pattern with the introduction of little metallic notches or tiny springs, as shown in the unit cell inset, which act as short circuits of the slots corresponding to the cuts defining the kirigami pattern in the closed configuration, while their presence has practically no effect when the FSS is stretched open.
