ScholarBank@NUS Repository. https://doi.org/10.1364/OE.17.023914||Abstract:||Modern metamaterials face functional constraints as they are commonly embedded in or deposited on dielectric materials. We provide a new solution by microfabricating a completely free-standing all-metal selfsupported metamaterial. Using upright S-string architecture with the distinctive feature of metallic transverse interconnects, we form a locally stiff, globally flexible space-grid. Infrared Fourier transform interferometry reveals the typical double-peak structure of a magnetically excited lefthanded and an electrically excited right-handed pass-band that is maintained under strong bending and heating, and is sensitive to dielectrics. Exploiting UV/X-ray lithography and ultimately plastic moulding, metafoils can be mass manufactured cost-effectively to serve as optical elements. ©2009 Optical Society of America.||Source Title:||Optics Express||URI:||http://scholarbank.nus.edu.sg/handle/10635/113008||ISSN:||10944087||DOI:||10.1364/OE.17.023914|
