We present numerically and experimentally a dynamic chiral metamaterial (MTM) that creates strong optical activity and circular dichroism. The proposed tunable structure has a very simple and more efficient configuration which introduces flexibility to adjust its EM properties. In addition, it gives a giant negative refractive index due to the high chirality. Our experimental results confirm the strong optical activity for a wide frequency range and agree with the simulation results. Moreover, the proposed chiral MTM provides a wideband and constant/flat chirality over a certain frequency band and thus it can be concluded that the developed chiral MTM based model offers a strong optical activity in terahertz, infrared and even in visible frequencies.

Flexible chiral metamaterials with dynamically optical activity and high negative refractive index Dincer, Furkan; KARAASLAN, MUHARREM; ÜNAL, EMİN; Akgol, Oguzhan; Sabah, Cumali (2015-07-10) We demonstrate numerically and experimentally chiral metamaterials (MTMs) based on gammadion-bilayer cross-wires that uniaxially create giant optical activity and tunable circular dichroism as a result of the dynamic design. In addition, the suggested structure gives high negative refractive index due to the large chirality in order to obtain an efficient polarization converter. We also present a numerical analysis in order to show the additional features of the proposed chiral MTM in detail. Therefore, a M...
Asymmetric transmission of linearly polarized electromagnetic waves using chiral metamaterials with constant chirality over a certain frequency band Akgöl, Oğuzhan; Dinçer, Furkan; Karaaslan, Muharrem; Ünal, Emin; Sabah, Cumali (World Scientific Pub Co Pte Lt, 2014-12-30) In this study, a dynamic chiral metamaterial (MTM) structure leading to an asymmetric electromagnetic (EM) wave transmission for linear polarization is presented. The structure is composed of square-shaped resonator with gaps on both sides of a dielectric substrate with a certain degree of rotation. The dynamic structure is adjustable via various parameters to fit any desired frequency ranges. Theoretical and experimental analysis of the proposed structure are conducted and given in detail. The suggested mo...
New generation planar chiral metamaterials with small and constant chirality over a certain frequency band Dincer, Furkan; Karaaslan, Muharrrem; Akgol, Oguzhan; ÜNAL, EMİN; Demirel, Ekrem; Sabah, Cumali (2015-01-10) Chiral metamaterial (MTM) researchers generally concentrate and aim to obtain large chirality with optical activity in certain frequencies. However, new generation planar chiral MTM which have small and constant/flat chirality over a certain frequency band have not queried by this time in literature. In fact, this area is mostly ignored by researchers. This study, first one according to best of our knowledge in the literature, is investigating the small and constant/fixed chirality and focuses on the new ge...
90 degrees Polarization rotator and antireflector using meanderline chiral metamaterials: Analytical and numerical approach Gonulal, Sengul; KARAASLAN, MUHARREM; ÜNAL, EMİN; DELİHACIOĞLU, KEMAL; Dincer, Furkan; TETİK, ERKAN; Sabah, Cumali (2015-01-01) We demonstrate theoretically and numerically a chiral slab that can exhibit optical activity, circular dichroism, and antireflection in detail. Copolar and crosspolar transmitted and reflected waves depending on permittivity, chirality and thickness are analyzed in order to display the characteristic features of the proposed chiral slab both for TE and TM incident waves. The suggested chiral slab is realized by a commercial full-wave EM solver to confirm theoretical results. From the results, the theoretica...
Full-Wave Computational Analysis of Optical Chiral Metamaterials Guler, Sadri; Solak, Birol; Gür, Uğur Meriç; Ergül, Özgür Salih (2017-09-27) We present computational analysis of optical chiral metamaterials that consist of helical metallic elements. At optical frequencies, metals are modeled as penetrable objects with plasmonic properties. A rigorous implementation based on boundary element methods and the multilevel fast multipole algorithm is used for efficient and accurate analysis of three-dimensional structures. Numerical results demonstrate interesting polarization-rotating characteristics of such arrays with helical elements, as well as t...
