In this study, broadside-coupled triangular split-ring-resonators are designed and simulated as THz sensors. Their double-side sensing capability provides sensitivity enhancement compared with single-sided sensors. The material to be detected is modeled as an over-layer on the structure. The ensuing change of the transmission resonances is investigated as a function in the thickness and permittivity of the substrate and of the one- or two-sided over-layer. The propagation direction of the incident wave also allows to select the excited mode (via the polarization of the radiation) which provides additional flexibility to the proposed sensor device by the possibility to operate it over a larger frequency range. Overall, the polarization dependency of the structure, the double-side sensing and the high sensitivity make such structures attractive as THz sensors.

Camera trajectory estimation for indoor robot odometry using stereo images and inertial measurements Horasan, Anıl; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2016) In this study, the development and implementation of an algorithm for stereo visual-inertial odometry are described. The study spans the complete process from analyzing the sensory data to the development of a robot odometry algorithm. The criteria for indoor visual-inertial odometry include using low-cost sensor systems, having an error less than five percent of the movement regardless of the distance covered, and building a robust algorithm in the presence of geometric and photometric invariances as well ...
Wide Bandwidth Absorption in the MWIR Region using a Thin and Simple Metamaterial Absorber ÜSTÜN, KADİR; Sayan, Gönül (2017-09-27) In this study, metamaterial absorber structures that operate in the mid-wave infrared (MWIR) region are presented. The advantage of the design stems from the high absorptance in the region of interest and the ease of fabrication. Fabrication stage is facilitated by large in-plane geometric dimensions of the metamaterial pattern and small thickness of the full absorber geometry.
Design and construction of a six degree of freedom platform Gürbüz, Sarper; Balkan, Raif Tuna; Department of Mechanical Engineering (2006) In this thesis a six degree of freedom (DOF) parallel manipulator is designed, developed and simulated virtually. The platform, which is specified and focused on in this thesis, is the specific solution for the generating the required data to simulate a land, airborne or sea vehicle’s motion trajectory in the laboratory environment. After explaining the need for such platforms for the military industry, the existing devices will be presented and discussed. Then the design period will be explained while poin...
Asymmetric transmission of linearly polarized electromagnetic waves using chiral metamaterials with constant chirality over a certain frequency band Akgöl, Oğuzhan; Dinçer, Furkan; Karaaslan, Muharrem; Ünal, Emin; Sabah, Cumali (World Scientific Pub Co Pte Lt, 2014-12-30) In this study, a dynamic chiral metamaterial (MTM) structure leading to an asymmetric electromagnetic (EM) wave transmission for linear polarization is presented. The structure is composed of square-shaped resonator with gaps on both sides of a dielectric substrate with a certain degree of rotation. The dynamic structure is adjustable via various parameters to fit any desired frequency ranges. Theoretical and experimental analysis of the proposed structure are conducted and given in detail. The suggested mo...
Stratified calibration and group synchronized focal length estimation for structure from motion algorithms Çalışkan, Akın; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2017) The estimation of unknown calibration parameters of the cameras without using any calibration pattern is critical for the performance of the 3D computer vision applications such as structure from motion, pose estimation, visual odometry, and it is still an open problem for the researchers. In this thesis, our contribution is two folded. First of all, we propose a novel stratified approach for estimating both the focal length and the radial distortion of a camera from given 2D point correspondences without k...
