Innovations in the manufacturing technology has led to an increase for the utilization of Terahertz (THz) region, which is also the most recent explored region of the electromagnetic spectrum. Although THz region is being used widely in various applications such as sensing, detecting, biological, and chemical, the region still requires further research and development of advanced devices. Metamaterials (MTMs) that are unnatural artificial materials are optimal for enhancing such devices operating by THz waves. In this context, Sub-THz MTM fishnet and absorber structures are designed and analyzed for the application of the THz region. Subsequently, the designs are theoretically analyzed and numerically evaluated with the verification of the perfect absorption rates. Additionally, the designs are tested as a MTM sensor that uses the resonant shifts to find the unknown materials. Moreover, two meta-switches are presented by doping of a photoconductive silicon to the proposed designs. Ultimately, two unique MTM structures have been introduced to the literature to be used in the future THz MTM applications and researches.

Development of a rapid-scan fiber-integrated terahertz spectrometer Keskin, Hakan; Altan, Hakan; Yavas, Seydi; İLDAY, Fatih Ömer; Eken, Koray; ŞAHİN, ASAF BEHZAT (2014-04-01) Scientists in terahertz (THz) wave technologies have benefited from the recent developments in ultrafast laser technologies and RF technologies and applied these new gained techniques into characterizing a wide variety of phenomena. Undoubtedly, the most successful of these applications has been in the development of time-domain terahertz spectroscopic and imaging systems which has been utilized in the characterization of dielectrics and semiconductors. This pulsed technique has allowed users to characteriz...
Simulation of an efficient silicon heterostructure solar cell concept featuring molybdenum oxide carrier-selective contact MEHMOOD, Haris; NASSER, Hisham; Tauqeer, Tauseef; HUSSAIN, Shahzad; Ozkol, Engin; Turan, Raşit (2018-03-25) Transition metal oxides/silicon heterocontact solar cells are the subject of intense research efforts owing to their simpler processing steps and reduced parasitic absorption as compared with the traditional silicon heterostructure counterparts. Recently, molybdenum oxide (MoOx, x<3) has emerged as an integral transition metal oxide for crystalline silicon (cSi)-based solar cell based on carrier-selective contacts (CSCs). In this paper, we physically modelled the CSC-based cSi solar cell featuring MoOx/intr...
Absorber and sensor applications of complimentary H-shaped fishnet metamaterial for sub-terahertz frequency region Faruk, Ahmet; Sabah, Cumali (Elsevier BV, 2019-01-01) The progress in the technology of manufacturing new materials increases the usage of Terahertz (THz) region, which is considered as the last explored region of electromagnetic spectrum. In biological, chemical, sensing and detecting applications THz region is started to be used widely. We proposed a unique fishnet metamaterial (MTM) absorber and metasensor that can be used to detect and characterize new materials which are produced for THz region. First of all, the reflection and absorption characteristics ...
Investigation of doped and undoped VOxfilms for terahertz microbolometer applications Atik, Bahar; Dirican, Emrah; Demirörs, Oytun; Altan, Hakan; Esentürk, Okan; Ylldlrlm, Mustafa; Akın, Tayfun (2021-01-01) The microbolometer technology has proved its potential in the Infrared (IR) region due to its low fabrication costs, and room temperature operation, making this technology desirable to be used in various applications, and this interest has recently expanded into the Terahertz (THz) region as well. The detection in microbolometers is achieved through the absorption of THz radiation which subsequently heats up and is sensed by the temperature sensitive material at the core of the device. This temperature sens...
Design and analysis of perfect metamaterial absorber in GHz and THz frequencies Dincer, Furkan; KARAASLAN, MUHARREM; Sabah, Cumali (2015-12-12) The new perfect metamaterial absorber (MA) based on square resonator with gap configuration is numerically (for GHz and THz frequency regime) and experimentally (for GHz frequency regime) presented and investigated. The proposed MA has a simple configuration which introduces flexibility to adjust its metamaterial properties and easily rescale the structure for other frequency regimes. In addition, polarization and incident angle independencies of the proposed model are analyzed for the THz frequency regime....
