Frequency selective surfaces for terahertz applications
(Bilkent University, 2015)This thesis presents Terahertz (THz) Frequency selective surfaces (FSS) that can be realized using standard microfabrication techniques. These FSS structures are designed for frequencies around 0.8 THz, which is a crucial ... -
Observation of gate-tunable coherent perfect absorption of terahertz radiation in graphene
(American Chemical Society, 2016)We report experimental observation of electrically tunable coherent perfect absorption (CPA) of terahertz (THz) radiation in graphene. We develop a reflection-type tunable THz cavity formed by a large-area graphene layer, ... -
Optically implemented broadband blueshift switch in the terahertz regime
(American Physical Society, 2011-01-18)We experimentally demonstrate, for the first time, an optically implemented blueshift tunable metamaterial in the terahertz (THz) regime. The design implies two potential resonance states, and the photoconductive semiconductor ... -
A performance-enhanced planar Schottky diode for Terahertz applications: an electromagnetic modeling approach
(Cambridge University Press, 2017)In this paper, we present the electromagnetic modeling of a performance-enhanced planar Schottky diode for applications in terahertz (THz) frequencies. We provide a systematic simulation approach for analyzing our Schottky ... -
Plasmonic enhanced terahertz time-domain spectroscopy system for identification of common explosives
(SPIE, 2017)In this study, we present a classification algorithm for terahertz time-domain spectroscopy systems (THz-TDS) that can be trained to identify most commonly used explosives (C4, HMX, RDX, PETN, TNT, composition-B and ... -
Terahertz Bandpass Frequency Selective Surfaces on Glass Substrates Using a Wet Micromachining Process
(Springer New York LLC, 2017)This paper presents terahertz (THz) frequency selective surfaces (FSS) implemented on glass substrate using standard microfabrication techniques. These FSS structures are designed for frequencies around 0.8 THz. A fabrication ...
