(a) Schematic of the multi-stacking and peel-off process of the metamaterial. (b) Transfer of the flexible metamaterial onto a VO₂ thin film on quartz, with the terahertz characterization scheme of the final MM. (c) Images of the flexible metamaterial, the peel-off process, and the fabricated sample.
