Fig. 1.

Design, assembly, and response of a proof-of-concept origami FSS assemblage with dipole elements of dimension 20 × 2 mm. Shown are prototypes of (A) Miura-FSS, (B) mirror-stacked Miura-FSS, and (C) inline-stacked Miura-FSS. (D) Miura-FSS unit cell with $a=b=20$ mm, $\alpha =45°$, and its folded configuration with folding angle $\theta$. (E) Assembly of two identical Miura-Ori layers into a mirror-stacked configuration and its unit cell. (F) Assembly of two Miura-Ori layers into an inline-stacked configuration and its unit cell, where the intrinsic geometry for the “white” unit cell is defined as $a=b=20$ mm, $\alpha =45°$, and for the “shaded” unit cell as $a=23.3\hspace{0.17em}\text{mm}$, $b=20\hspace{0.17em}\text{mm}$, $\alpha =52°$ (see SI Appendix for details). (G) Frequency response in terms of transmission coefficient ${\mathrm{S}}_{21}$ for the single-layer, mirror-stacked, and inline-stacked Miura-Ori assemblages for folding angles $\theta =60°,90°,120°$ corresponding to panel extensions of 50%, 71%, 87%, respectively, and considering a normal angle of incidence (AoI) with a linearly polarized electric field E that is oriented along the length of the dipole elements. (H) Frequency response in terms of transmission coefficient ${\mathrm{S}}_{21}$ for the single-layer, mirror-stacked, and inline-stacked Miura-Ori assemblages for folding angle $\theta =90°$ (i.e., 71% extension) and AoI = $0°,30°,75°$.
