Flexible metamaterials at visible wavelengths

Optical metasurfaces with robust angular response on flexible substrates

“…12,15 In this paper, we experimentally verify the angular independence of the optical response of plasmonic metasurfaces and apply them to the flexible substrate technology, recently developed in Ref. 9. We show numerically and experimentally that this kind of FSS implements a filter transfer function as depicted in the artistic rendering in Fig.…”

“…6) and near infrared 7 range, and very recently at visible frequencies. 8,9 In this context, recent interest in "metasurfaces" and "metafilms," the two-dimensional (2D) version of metamaterials, has been highlighted in several papers. [10][11][12] Their design and characterization are in many senses consistent with the design of frequency-selective surfaces (FSSs), a common technology at microwave frequencies for filtering applications.…”

Electrodeposition of gold templated by patterned thiol monolayers

“…This bears some analogy to metal evaporation onto SAMs where the neutral species impinge on the outer surface of the SAM and then penetrate through to the substrate. Both Au and Cu have been found to penetrate SAMs with chemically inert terminal groups such as CH 3 and no explicit differences in their penetration behaviour has been reported [58,71,72].…”

“…The optical and electrical properties of metallic micro-and nanostructures are of interest for a wide range of applications which comprise plasmonics and metamaterials [1][2][3][4], energy conversion [5], displays [6], and sensing [7][8][9][10][11][12][13]. Besides their technical specification, one important criterion influencing their technological implementation is the effort required to generate such structures and in search for viable routes a widely adopted strategy is based on templating.…”

Numerical study on a photonic crystal waveguide that includes a dispersive metamaterial

“…The photonic crystals that constitute periodic arrays of different materials with a unit cell of dimension on the order of the wavelength have the potential to develop a new technology of integrated optical circuits [3,4]. Other kinds of structured materials that have recently attracted much interest are the dispersive metamaterials or left-handed materials (LHMs), which owe their name to the fact that the light vectors E, H and k form a left handed triad for a wave propagating through these media [5][6][7]. This work is concerned with determination of the plasmonic surface modes of a photonic crystal waveguide, formed with two perfect electric conductor (PEC) flat surfaces and a periodic array of circular inclusions of dispersive LHM.…”
