The aim of this work is to investigate new classes of artificial materials exhibiting unconventional properties in order to build novel devices operating in the Terahertz regime. We focus on the design, fabrication and characterization of tunable metamaterials with unit cells based on Split Ring Resonators. By incorporation of a nematic liquid crystal in the structure, we observe a frequency shift in the resonant response over 10% in bandwidth and more than 10 dB change in the signal absorption. We discuss how such a hybrid structure can be exploited for the development of a THz spatial light modulator.

Super-Resolution Image Reconstruction Applied to an Active Millimeter Wave Imaging System based on Compressive Sensing Alkus, Umit; Ermeydan, Esra Sengun; ŞAHİN, ASAF BEHZAT; ÇANKAYA, İLYAS; Altan, Hakan (2017-09-11) The development of passive and active millimeter wave imaging systems is progressing rapidly fueled by the need for many applications in the area of security and defense. Imaging schemes that may either utilize array detectors or single detectors in scan architectures offer suffer from poor resolution due to the longer wavelengths used and the limits of the optical system in terms of lens and mirror dimensions. In order to overcome this limit, super-resolution techniques can be employed to enhance the resol...
Hydrothermal method for doping of zinc oxide nanowires and fabrication of ultraviolet photodetectors Afal, Ayşegül; Ünalan, Hüsnü Emrah; Turan, Raşit; Department of Metallurgical and Materials Engineering (2012) Nanotechnology comprises of the understanding and control of materials and processes at the nanoscale. Among various nanostructured materials, semiconducting nanowires attract much interest for their novel physical properties and potential device applications. The unique properties of these nanowires are based on their high surface to volume ratio and quantum confinement effect. Zinc oxide, having a direct, wide bandgap and large exciton binding energy, is highly appealing for optoelectronic devices. Due to...
Vibration reduction by the use of beam-type metastructures with nonlinear attachments Özceylan, Bekir Mert; Ciğeroğlu, Ender; Ertürk, Alper; Department of Mechanical Engineering (2022-11-30) Metamaterials are artificial materials engineered to have special properties which are not possessed by natural materials. Metastructures are metamaterial-based finite structures with specified boundary conditions coupled with an array of resonators. Due to their resonant nature, metastructures can have bandgaps at very long wavelengths compared to their lattice size. Previous studies have shown that this phenomenon arises as dynamic effective mass becomes negative around a local resonance frequency interva...
Ductile–brittle failure of amorphous glassy polymers: A phase-field approach Dal, Hüsnü; Gültekin, Osman; BAŞDEMİR, SELÇUK; Açan, Alp Kağan (2022-11-01) © 2022 Elsevier B.V.Optimal use and design of amorphous glassy polymers in goods have become a significant task in the key industrial sectors ranging from micro-electronics to aerospace and medical industry. Depending on the microstructure, temperature level and the external loading rate to which these polymers are subjected, the fracture response may change from ductile to brittle or vice versa. While the ductile response is manifested by diffuse shear zones exhibiting volume-preserving inelastic deformati...
