ISAR imaging and motion compensation
Küçükkılıç, Talip; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2006)
In Inverse Synthetic Aperture Radar (ISAR) systems the motion of the target can be classified in two main categories: Translational Motion and Rotational Motion. A small degree of rotational motion is required in order to generate the synthetic aperture of the ISAR systems. On the other hand, the remaining part of the target’s motion, that is any degree of translational motion and the large degree of rotational motion, degrades ISAR image quality. Motion compensation techniques focus on eliminating the effe...

Ultrasonic characterisation of hot-rolled and heat-treated plain carbon steels
Gür, Cemil Hakan (British Institute of Non-Destructive Testing (BINDT), 2003-09-01)
The aim of the study is to characterise hot-rolled and heat-treated plain-C steels (SAE 1020 and 1050) by ultrasonic velocity and attenuation measurements. Various heat treatment procedures were applied by changing the austenitisation temperature and the cooling rate to distinguish the affects of grain size and microstructural phases on ultrasonic properties. Velocities of both longitudinal and transversal waves were measured and backwall echo patterns were obtained for each specimen. The variations in the ...
Metamaterial absorber-based sensor embedded into X-band waveguide
SABAH, CUMALİ; TURKMEN-KUCUKSARİ, OZNUR; Sayan, Gönül (Institution of Engineering and Technology (IET), 2014-07-17)
A novel metamaterial sensor, integrated with an X-band waveguide, is proposed for high-resolution measurements of variations in the dielectric constant and/or the thickness of a superstrate layer that covers a pair of absorber unit cells. Variations in superstrate parameters are potentially caused by physical, chemical or biological factors, and can be detected by measuring the corresponding shifts in the resonance frequency of the metamaterial sensor. It is estimated by simulation results that resolution l...
Metamaterial-based energy harvesting for GSM and satellite communication frequency bands
BAKIR, MEHMET; KARAASLAN, MUHARREM; KARADAĞ, FARUK; ÜNAL, EMİN; AKGÖL, OĞUZHAN; ALKURT, FATİH ÖZKAN; Sabah, Cumali (2018-08-01)
A metamaterial-based energy harvesting structure has been designed and experimentally tested in this study. The proposed structure has square and split ring resonators placed in different angles on the back and front sides for compatible multiband operation in energy harvesting. Resonance points have been defined at 900 MHz, 1.37 GHz, 1.61 GHz, 1.80 GHz, and 2.55 GHz, by simulation and experimental methods. These points correspond to Global System for Communication (GSM) 900, GSM 1800, Universal Mobile Tele...
