90° degrees Polarization rotator and antireflector using meanderline chiral metamaterials: Analytical and numerical approach

Gönülal, Şengül; Karaaslan, Muharrem; Ünal, Emin; Delihacıoğlu, Kemal; Dinçer, Furkan; Tetik, Erkan; Sabah, Cumali (Elsevier GmbH, 2015)

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, ...

Dynamic and tunable chiral metamaterials with wideband constant chirality over a certain frequency band

Dinçer, Furkan; Karaaslan, Muharrem; Akgöl, Oğuzhan; Ünal, Emin; Sabah, Cumali (Elsevier GmbH, 2015)

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 ...
