Gold Helix Photonic Metamaterial as Broadband Circular Polarizer
Justyna K. Gansel,Michael Thiel,Michael S. Rill,Manuel Decker,Klaus Bade,Volker Saile,Georg von Freymann,Stefan Linden,Martin Wegener +8 more
TL;DR: This work investigated propagation of light through a uniaxial photonic metamaterial composed of three-dimensional gold helices arranged on a two-dimensional square lattice that is scalable to other frequency ranges and can be used as a compact broadband circular polarizer.
Tailored 3D mechanical metamaterials made by dip-in direct-laser-writing optical lithography.
Tiemo Bückmann,Nicolas Stenger,Muamer Kadic,Johannes Kaschke,Andreas Frölich,Tobias Kennerknecht,Christoph Eberl,Michael Thiel,Martin Wegener +8 more
TL;DR: Bow-tie elements assembled into mechanical metamaterials with positive/zero/negative Poisson's ratio and with sufficient overall size for direct mechanical characterization aim at demonstrating the new possibilities with respect to rationally designed effective materials.

An elasto-mechanical unfeelability cloak made of pentamode metamaterials
TL;DR: This work designs an approximate elasto-mechanical core-shell 'unfeelability' cloak based on pentamode metamaterials and quasi-statically deform cloak and control samples in the linear regime and map the displacement fields by autocorrelation-based analysis of recorded movies.
On the feasibility of pentamode mechanical metamaterials
TL;DR: In this paper, a pentamode metamaterial was fabricated by dip-in direct-laser-writing optical lithography and the figure of merit for the ratio of bulk modulus to shear modulus was shown to be as large as about 1,000.

TL;DR: In this article, planar magnetic photonic metamaterials were fabricated via direct laser writing and silver chemical vapor deposition, an approach which is also suitable for three-dimensional structures, revealing the importance of bi-anisotropy.
