This article investigates the electromagnetic wave-absorbing properties of SiC-based ceramic woven fabrics. The electrical conductivity of ceramic woven fabrics was modified by heat treatment in air, resulting in oxidation, and the electromagnetic wave absorption potential of single- and double-layer ceramic woven fabrics were determined in the 17-40 GHz frequency range using the free-space method. The absorption potentials of ceramic woven fabrics of different chemical composition and weave were correlated with their material properties through X-ray diffraction, scanning electron microscopy, and electrical resistance measurement. The effect of the different arrangements of fabrics in multilayer forms, and how oxidation affects the electromagnetic wave absorption potential of the fabrics are discussed. Various double-layer combinations of SiC-based woven fabrics revealed promising potentials for both reduced reflection and transmission, resulting in similar to 90% absorption in the GHz range, which makes them powerful candidate materials for electromagnetic wave absorption applications.

Characterization of electromagnetic wave absorbing properties of sic-based and alumina ceramic woven fabrics Tan, Elvan; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2008) Electromagnetic wave absorbing properties of SiC-based and alumina ceramic woven fabrics have been investigated. Electrical conductivities of SiC-based ceramic woven fabrics were modified by heat treatment in air resulting in their oxidation. Surface properties of alumina woven fabrics were altered by gold-sputtering resulting in a high conductivity layer on the surface of the wovens. Electromagnetic wave interactions of single layer and double layered combinations of these ceramic woven fabrics were determ...
Absorption edge and optical constants of Tl2Ga2S3Se crystals from reflection and transmission, and ellipsometric measurements Isik, M.; Hasanlı, Nızamı (2012-06-15) The optical properties of Tl2Ga2S3Se layered crystalline semiconductors were investigated from transmission, reflection and ellipsometric measurements. The experimental results of the room temperature transmission and reflection measurements performed in the wavelength range of 400-1100 nm showed the presence of both indirect and direct transitions in the band structure of the crystals with 2.38 and 2.62 eV band gap energies.
Electromagnetic absorbance properties of a textile material coated using filtered arc-physical vapor deposition method ESEN, MEHMET; İLHAN, İLHAMİ; KARAASLAN, MUHARREM; ÜNAL, EKİN ANIL; Dincer, F.; Sabah, C. (2015-09-01) We explore the structure of a textile absorber in terms of its electromagnetic and absorption properties in the microwave region. Its absorption characteristics are similar to those reported for various metamaterial-based absorbers, exhibiting absorption as high as 98% at resonance. In addition, the angular behavior of the absorption properties of the sample reveal incident angle independency, which is the other added value of the study. Also, the suggested textile absorber has a simple configuration, which...
Functionalization of glass fiber woven fabrics by ITO coatings and characterization of their electromagnetic properties Özdil Darıcıoğlu, Merve; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2022-1-14) ITO sols were deposited on glass fiber woven fabrics by spray pyrolysis technique and electrical conductivity of these layers was controlled to incorporate electromagnetic (EM) wave absorbing characteristics to glass fabrics. The surface functionalized fabrics were used as reinforcement in a hybrid type multilayer EM wave absorbing composite which is a combination of Jaumann and graded type absorbers effective in 8-12 GHz frequency range (X-band). The effects of the conductivity and the cascading order for ...
Usability of polylactide biopolymer as thermoplastic matrix for woven fiber composite laminates Demirok, Gökberk; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2022-4-28) The first purpose of this study was, as the first time in the literature, to investigate usability of polylactide (PLA) biopolymer as the matrix of high-performance composite laminated structures having woven forms of glass and carbon fibers. For this purpose, 2-14 layers of 2x2 twill Carbon Fiber (CF) and 1x1 plain weave Glass Fiber (GF) forms were stacked by PLA powders followed by consolidation of these layers by compression molding technique. After conducting various tests and analysis it was observed t...
