Abstract-Reversibly Stretchable and Tunable Terahertz Metamaterials with Wrinkled Layouts

http://onlinelibrary.wiley.com/doi/10.1002/adma.201200419/abstract
The use of wrinkling provides a generic route to stretchable metamaterials, with unprecedented terahertz tunability. The wrinkled metamaterial can be stretched reversibly up to 52.5%; the structural integrity can be maintained during at least 100 stretching/relaxing cycles. Importantly, the wrinkling of meta-atoms offers a deterministic way to achieve controlled broadening of electrical resonance.
