We present a detailed discussion of the three-interface surface plasmon resonance (SPR) geometry with the "angular interrogation" approach, and study the effect of thermal changes on the SPR curve through numerical simulations. An optical temperature sensor based on SPR, which has been shown to be a promising method to be used in the development of chemical, physical, and biomedical sensors, is proposed. The temperature sensor employs a three-interface SPR geometry where the layer making the interface with the environment has a refractive index highly sensitive to the changes in, the temperature of the environment. The resolution of the temperature measurement is dependent on the angular resolution of the detection system and the temperature sensitivity of the sensing layer. The comparison of thermal sensitivities of three and two-interface SPR geometries is also presented.

Theory and applications of surface plasmon resonance sensors Özdemircan, Furkan; Sayan, Gönül; Department of Electrical and Electronics Engineering (2021-2-12) In this thesis, the electromagnetic theory of the surface plasmon resonance (SPR) phenomenon and its applications in optical sensing are investigated. An SPR sensor's operation is based on the excitation of surface plasmon waves (SPWs) at an interface between two different media, a metal layer, and a dielectric layer, with real parts of dielectric constants having opposite signs. The presence of the SPR shows itself with a sharp minimum in the reflection curve of the sensor that is operated by either the an...
Evolutionary topology optimization of a folding missile wing for stiffness and frequency Ürün, Ata; Şahin, Melin; Gürses, Ercan; Department of Aerospace Engineering (2023-1-25) This thesis presents a study on the topology optimization of a folding wing structure for a cruise missile with the aim of minimizing the weight of the wing while maximizing its stiffness and/or maximizing the selected natural frequency values. The weight of the folding wing has a significant impact on the performance of the opening mechanism and the overall dynamic behavior of the missile. The Bidirectional Evolutionary Structural Optimization (BESO) method, a widely-used topology optimization technique, i...
Nonlinear resonances of axially functionally graded beams rotating with varying speed including Coriolis effects Lotfan, Saeed; Anamagh, Mirmeysam Rafiei; Bediz, Bekir; Ciğeroğlu, Ender (2021-11-01) The purpose of the current study was to develop an accurate model to investigate the nonlinear resonances in an axially functionally graded beam rotating with time-dependent speed. To this end, two important features including stiffening and Coriolis effects are modeled based on nonlinear strain relations. Equations governing the axial, chordwise, and flapwise deformations about the determined steady-state equilibrium position are obtained, and the rotating speed variation is considered as a periodic distur...
Numerical investigation of characteristics of pitch and roll damping coefficients for missile models Kayabaşı, İskander; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2012) In this thesis the characteristics of pitch and roll damping coefficients of missile models are investigated by using Computational Fluid Dynamics (CFD) techniques. Experimental data of NACA0012 airfoil, Basic Finner (BF) and Modified Basic Finner (MBF) models are used for validation and verification studies. Numerical computations are performed from subsonic to supersonic flow regimes. Grid refinement and turbulence model selection studies are conducted before starting the dynamic motion simulations. Numer...
Thermal Sensitivity of the Fundamental Natural Frequency of a Resonant MEMS IR Detector Pixel Pala, Sedat; Azgın, Kıvanç (2017-08-10) This paper presents the effect of temperature on the natural frequency of (1,1) mode shape of a Resonant MEMS IR bolometer pixel in the range of 295-340 K. The detector pixel has a square plate geometry having side length of 1400 mu m and thickness of 35 mu m. The resonating plate is supported at its geometric center, enabling more robust pixels with fill factor greater than 90% and less complicated fabrication process. The sensor is fabricated using a Silicon-On-Glass (SOG) process. For the first time in t...
