Exploration of the perfect combination between metamaterials (MTMs) and plasmonics has paved the way of the new innovations in electromagnetic and communication engineering, especially in sub-THz spectroscopy. In order to contribute to such developments, plasmonic resonances in sub-THz fishnet MTM on the basis of complementary hexagonal resonator structure is investigated in this paper. The design, in which method of removing hexagonal structure is applied, has been performed based on finite simulation technique. Five distinct plasmonic resonances are determined at some of the specific frequency spots where interactions between electron plasmas and incident electromagnetic waves can be observed. The proposed material can be employed in several subtopics of electromagnetic engineering such as high pass filters and antenna applications. Furthermore, thanks to the THz wave confinement property of this plasmonic structure, incident THz waves can be controlled efficiently and therefore, the proposed MTM can be tailored at THz spectroscopy and imaging, localization of the THz wave and energy, sensors and photonics applications, effectively.

Absorber and sensor applications of complimentary H-shaped fishnet metamaterial for sub-terahertz frequency region Faruk, Ahmet; Sabah, Cumali (Elsevier BV, 2019-01-01) The progress in the technology of manufacturing new materials increases the usage of Terahertz (THz) region, which is considered as the last explored region of electromagnetic spectrum. In biological, chemical, sensing and detecting applications THz region is started to be used widely. We proposed a unique fishnet metamaterial (MTM) absorber and metasensor that can be used to detect and characterize new materials which are produced for THz region. First of all, the reflection and absorption characteristics ...
Opto-thermoelectric nanotweezers LIN, Linhan; WANG, Mingsong; PENG, Xiaolei; LISSEK, Emanuel N.; MAO, Zhangming; SCARABELLI, Leonardo; ADKINS, Emily; Coskun, Sahin; Ünalan, Hüsnü Emrah; KORGEL, Brian A.; LIZ-MARZAN, Luis M.; FLORIN, Ernst-Ludwig; ZHENG, Yuebing (Springer Science and Business Media LLC, 2018-04-01) 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-...
Quantitative analysis of nonlinear dynamics of quantum light transmission in strongly coupled quantum dot-cavity systems Tugen, Alperen; Kocaman, Serdar (Elsevier BV, 2019-04-01) We compared transmission spectra of coupled high-Q cavity with quantum dot (QD) systems in the strong coupling regime with Input-Output Formalism (IOF) and Incoherent Pumping Mechanism (IPM) based on Lindblad master equation approach. The peak transmission of Dipole Induced Transparency (DIT) together with its full-width-half-maximum (FWHM) are enquired for detailed analysis. Both methods exhibit the same vacuum Rabi splitting in on-resonant case, in contrast, the peak of DIT is estimated smaller between 50...
Quantum Transport Mode in Graphene Nanoribbon Based Transistor Hedayat, Sayed Norollah; Ahmadi, Mohammad Taghi; Sedghi, Hassan; Goudarzi, Hadi; Moradi, Shahram (American Scientific Publishers, 2017-09-01) Graphene has incredible carrier transport property with high application opportunity at single molecule level, which composes it as promising materials on nano electronic application. In order to develop the new device such as graphene nanoribbon transistor, Carbon Nanotube Field Effect Transistor (CNTFET) and nanowire based devices, it is essential to investigate the quantum limit in low dimensional systems. In this paper transmission coefficient of the schottky structure in the graphene based transistor i...
Electronic structure of carbon nanotubes: AM1-RHF calculations Erkoç, Şakir; Turker, L (Elsevier BV, 1999-07-01) We have investigated the electronic structure of optimized open-ended single-wall carbon nanotubes with armchair and zigzag geometries. The calculations were performed using AM1-RHF semiempirical molecular orbital method. It has been found that the density of states of the zigzag model is more sensitive to the tube size than that of the armchair model.
