Local density of electromagnetic states within a nanometric gap formed between two thin films supporting surface phonon polaritons
(AIP Publishing, 2010)We present a detailed physical analysis of the near-field thermal radiation spectrum emitted by a silicon carbide (SiC) film when another nonemitting SiC layer is brought in close proximity. This is accomplished via the ... -
Localized near-field radiative heat transfer in biomimicry designs inspired by neon tetra fish
(Begell House Inc., 2019-06)Inspired by multilayer structure of the Neon tetra tropical fish which is one of the most fascinating multilayer systems ever reported in nature, we investigate the localized effects of coupling of surface phonon polaritons ... -
Localized radiative energy transfer from a plasmonic bow-tie nano-antenna to a magnetic thin film stack
(Springer Business+Media, 2011-06)Localized radiative energy transfer from a near-field emitter to a magnetic thin film structure is investigated. A magnetic thin film stack is placed in the near-field of the plasmonic nano-antenna to utilize the evanescent ... -
Low-cycle fatigue behavior of friction stir-welded copper joints
(Springer, 2021-11)Investigation of the fatigue response of friction stir-welded (FSWed) joints is especially important in the design and manufacturing of components with exposure to cyclic loading. In this study, cyclic response of FSWed ... -
Low-loss optical switch using Brewster angle
(IEEE, 2011)Fabrication and actuation errors of submicron silicon waveguide optical switches are reported to remain within sub-100 nm ranges. These errors cause high loss ruining the optical performance of the switches at the on-state. ... -
Lower uncertainty bounds of diffraction-based nanoparticle sizes
(Wiley, 2022-06)A self-consistent analysis is reported of traditional diffraction-based particle size determination techniques applied to synthetic diffraction profiles generated with the Patterson approach. The results show that dimensions ... -
Machine learning to predict junction temperature based on optical characteristics in solid-state lighting devices: A test on WLEDs
(MDPI, 2022-08)While junction temperature control is an indispensable part of having reliable solid-state lighting, there is no direct method to measure its quantity. Among various methods, temperature-sensitive optical parameter-based ... -

Mass flow rate control of solenoid-based injectors
(Sage, 2023-09)This paper presents a mass flow rate control method for solenoid-based injectors in open-loop, i.e. without physical sensor feedback. Measuring the mass flow rate in injectors is important because the performance of the ... -
Materials for radiative cooling: a review
(Elsevier, 2017)Buildings use more than one-third of the total energy consumed in counties within the Mediterranean climate zones like in Turkey. During the summer months, the absorption of solar energy by the buildings increases the ... -
Mechanical and wear properties of ultrafine-grained pure Ti produced by multi-pass equal-channel angular extrusion
(Elsevier, 2009-08-20)In this study, pure grade 2 Ti was processed via equal-channel angular extrusion (ECAE) for 8 and 12 passes following route-E at 300 °C. After processing, the microstructural evolution, tensile properties and wear behavior ... -
Mechanical behavior of constrained groove pressed stainless steel and pure zinc
(Trans Tech Publications Ltd, 2021)Constrained groove pressing (CGP), a severe plastic deformation method, has been implemented on AISI 304 and commercially pure zinc samples in the present work. Four CGP passes were successfully applied to both materials ... -
