Sensory applications of resonator based metamaterial absorber

Sabah, C.
Metamaterials are attractive media for scientific society for their potential multi-functional and a wide range of applications due to their unusual electromagnetic properties. In this paper, we present several important applications including pressure, density and volumetric moisture sensing based on rectangular split ring structure with a strip line. These applications are carried out experimentally and numerically. Since the sensing ability is mostly connected with the resonance frequencies, we have carefully selected a frequency range where the resonance shifts occur linearly depending on the pressure and the density of the medium or material to be tested. The proposed model can be used for chemical, agricultural, medical and biological sensing applications in the microwave frequency band. The model is composed of a split ring resonator (SRR) topology and the sensing layer sandwiched between the SRR and a rectangular copper layer located at the background. Middle-sensing layer changes its dielectric behavior linearly depending on the pressure and the density allowing us to determine the unknown values of these parameters.

Optical manipulation of plasmonic nanoparticles provides opportunities for fundamental and technical innovation in nanophotonics. Optical heating arising from the photon-to-phonon conversion is considered as an intrinsic loss in metal nanoparticles, which limits their applications. We show here that this drawback can be turned into an advantage, by developing an extremely low-power optical tweezing technique, termed opto-thermoelectric nanotweezers. By optically heating a thermoplasmonic substrate, a light-...

AgInSe2 and In2Se3 are two attractive semiconducting materials for various technological applications especially for photovoltaic applications. In the present study, structural and optical properties of (AgInSe2)(x)-(In2Se3)(1-x) crystals for composition of x = 0.75 corresponding to chemical formula of Ag3In5Se9 were characterized by X-ray diffraction, energy-dispersive spectroscopy, room temperature transmission, and ellipsometry experiments. The transmittance spectrum was analyzed to reveal energy band ga...
Performance evaluation of similarity measures for dense multimodal stereovision
Yaman, Mustafa; Kalkan, Sinan (SPIE-Intl Soc Optical Eng, 2016-05-01)
Multimodal imaging systems have recently been drawing attention in fields such as medical imaging, remote sensing, and video surveillance systems. In such systems, estimating depth has become possible due to the promising progress of multimodal matching techniques. We perform a systematic performance evaluation of similarity measures frequently used in the literature for dense multimodal stereovision. The evaluated measures include mutual information (MI), sum of squared distances, normalized cross-correlat...
Vibrational modes in (TlGaS2)(x)-(TlGaSe2)(1-x)mixed crystals by Raman measurements: compositional dependence of the mode frequencies and line-shapes
Isik, M.; Terlemezoglu, M.; Hasanlı, Nızamı; Babayeva, R. F. (Springer Science and Business Media LLC, 2020-09-01)
TlGaS(2)and TlGaSe(2)ternary semiconducting compounds have been of scientific interest due to their large ultrafast optical nonlinearity characteristics. These remarkable properties make them promising semiconducting materials in photonic applications. A series of (TlGaS2)(x)-(TlGaSe2)(1-x)layered mixed crystals grown by Bridgman method were investigated from the standpoint of their Raman spectroscopy characteristics. Experimental Raman scattering study of crystals were reported in the frequency range of 80...

Terlemezoğlu, Makbule; Dogru, C.; Gullu, H. H.; Çiftpınar, Emine Hande; Parlak, Mehmet (Springer Science and Business Media LLC, 2019-06-01)
The focus of this study is the characterization of Cu2ZnSn(S,Se)(4) (CZTSSe) thin films and fabrication of CZTSSe solar cell in superstrate configuration. In this work, superstrate-type configuration of glass/ITO/CdS/CZTSSe/Au was entirely fabricated by totally vacuum-based process. CZTSSe absorber layers were grown by RF magnetron sputtering technique using stacked layer procedure. SnS, CuSe and ZnSe solid targets were used as precursors and no additional step like the selenization process was applied. The...
