Characterization of chiral metamaterial sensor with high sensitivity

Dalgaç, Şekip; Bakır, Mehmet; Karadağ, Faruk; Ünal, Emin; Karaaslan, Muharrem; Sabah, Cumali (Elsevier GmbH, 2020)

In this study, a chiral metamaterial sensor applications are created by placing asymmetrically two meander line front and back side of the substrate layer. Characterization of the dielectric constant, thickness and loss ...

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, ...

Zinc oxide-tungsten-based pyramids in construction of ultra-broadband metamaterial absorber for solar energy harvesting

Ünal, Emin; Bağmancı, Mehmet; Karaaslan, Muharrem; Akgöl, Oğuzhan; Arat, Hüseyin Turan; Sabah, Cumali (Institution of Engineering and Technology, 2017)

A new broadband absorber is investigated for the entire frequency domain of solar light (infrared, visible light and ultraviolet). While current absorbers in the literature have limited operation frequencies, investigated ...

Extremely-broad band metamaterial absorber for solar energy harvesting based on star shaped resonator

Bağmancı, Mehmet; Karaaslan, Muharrem; Ünal, Emin; Akgöl, Oğuzhan; Sabah, Cumali (Springer, 2017)

A new metamaterial absorber (MA) is investigated and shown numerically for solar energy harvesting for future solar cell applications. The structure consists of two metals and one dielectric layer having different thicknesses. ...

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 ...

Sensory applications of resonator based metamaterial absorber

Bakır, Mehmet; Karaaslan, Muharrem; Akgöl, Oğuzhan; Altıntaş, Olcay; Ünal, Emin; Sabah, Cumali (Elsevier GmbH, 2018)

Metamaterials are attractive media for scientific society for their potential multi-functional and a wide range of applications due to their unusual electromagnetic properties. In this paper, we present several important ...
