Fig. 2.

Simulated response of the Miura-Ori–based FSS, in which the internal lines represent the resonant frequency, and the top and bottom lines represent the cutoff frequencies at −10 dB. Shown is the response of the FSS structures with distinct panel angles $\alpha =52°,56°,60°,64°,70°$ (in the case of inline stacking, $\alpha ={\alpha }_t$, i.e., the angle $\alpha$ for the top layer). (A–C) For a specific AoI$\hspace{0.17em}=\hspace{0.17em}0°$ and distinct folding angles $\theta =60°,90°,120°$ for single-layer, mirror-stacked, and inline-stacked Miura-FSS, respectively. (D–F) For a specific folding angle $\theta =90°$ and distinct AoI = $0°,30°,75°$ considering single-layer, mirror-stacked, inline-stacked Miura-FSS, respectively.
