In this work, a new multiband terahertz metamaterial absorber is designed and characterised by numerical simulation method. In addition, the utilisation of the proposed absorber as a sensor is also investigated. The dielectric and thickness sensing characteristics are analysed. The proposed multiband metamaterial absorber has the ability for utilising the terahertz region up to 2 THz. According to the results, it is found that the proposed absorber is capable of sensing unknown materials and material thickness with any of its five absorption bands. The sensitivity of the proposed sensor is 6.57 GHz / unit sensitivity for dielectric sensing and for thickness sensing.

Diamond-shaped hole array in double-layer metal sheets for negative index of refraction Yilmaz, A.; Sabah, C. (2013-03-01) In this paper, a new design of hole array in a double-layer periodic arrangement is introduced and investigated both numerically and experimentally for the negative index of refraction. The structure shows similar behavior to that of the corresponding fishnet metamaterials. The effective constitutive parameters are revealed by using retrieval procedure to verify the negative refraction nature of the proposed structure. A relatively high figure of merit (FOM=Re(n)/Im(n)=70.05) is achieved at the K-band (1826...
ANALYSIS OF MILLIMETER WAVE-GUIDES ON ANISOTROPIC SUBSTRATES USING THE 3-DIMENSIONAL TRANSMISSION-LINE MATRIX-METHOD BULUTAY, C; PRASAD, S (1993-06-01) Three-dimensional condensed asymmetrical node, variable grid, transmission-line matrix (TLM) method has been used in analyzing several millimeter waveguides on anisotropic substrates. The dispersion characteristics of image guides together with field and energy confinement properties at millimeter-wave frequencies have been investigated. Edge coupled microstrip line on a uniaxial substrate is analyzed for the even and odd mode dispersion characteristics. Finally the same analysis is repeated for bilateral f...
QUANTUM-CLASSICAL MIXED-MODE ANALYSIS OF NONLINEARLY COUPLED OSCILLATORS - A TIME-DEPENDENT SELF-CONSISTENT-FIELD APPROACH YURTSEVER, E; BRICKMANN, J (1992-02-01) A two-dimensional vibrational system with a strong nonlinear coupling is studied using a quantum-classical mixed mode self-consistent-field approach. The classical equations of motion as well as the time-dependent Schrodinger equation are solved for respective modes under the influence of the average fields generated by the other modes. This vibrational system was previously shown to be chaotic under classical mechanical treatment but quantum mechanical observations pointed out to highly regular behaviour...
Multi-band metamaterial absorber topology for infrared frequency regime Mulla, Batuhan; Sabah, Cumali (2017-02-01) In this paper, a new multiband metamaterial absorber design is proposed and the numerical characterization is carried out. The design is composed of three layers with differently sized quadruplets in which the interaction among them causes the multiband absorption response in the infrared frequency regime. In order to characterize the absorber. and explain the multiband topology, some parametric studies with respect to the dimensions of the structure are carried out and the contributions of the quadruplets ...
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 ...
