The magical world of metamaterials
(SPIE, 2009)
We review experimental and theoretical studies performed on left-handed metamaterials (LHM). The metamaterials exhibit quiet unusual electromagnetic properties such as negative refraction, negative phase velocity, subwavelength ...
Metamaterial-based wireless RF-MEMS strain sensors
(IEEE, 2010)
Approximately 10% of the fractures do not heal properly because of the inability to monitor fracture healing. Standard radiography is not capable of discriminating whether bone healing is occurring normally or aberrantly. ...
Observation of negative refraction and focusing in two-dimensional photonic crystals
(Institute of Physics Publishing Ltd., 2006)
We experimentally and theoretically demonstrate the negative refraction and focusing of electromagnetic (EM) waves by twodimensional photonic crystal slabs at microwave frequencies. The negative refraction is observed both ...
Theoretical study and experimental realization of a low-loss metamaterial operating at the millimeter-wave regime: demonstrations of flat-and prism-shaped samples
(IEEE, 2009-10-23)
We designed a low-loss double-negative composite metamaterial that operates at the millimeter-wave regime. A negative passband with a peak transmission value of 2.7 dB was obtained experimentally at 100 GHz. We performed ...
Miniaturization and characterization of metamaterial resonant particles
(IEEE, 2008-10)
This paper is focussed on the miniaturization and characterization of semi-lumped resonators, of interest for the synthesis of metamaterial-based structures such as metamaterial transmission lines, frequency selective ...
Design of miniaturized narrowband absorbers based on resonant-magnetic inclusions
(IEEE, 2011-06-21)
In this paper, we present the design of miniaturized narrowband-microwave absorbers based on different kinds of magnetic inclusions. The operation of the proposed components originates from the resonance of a planar array ...
Semiconductor thin film based metasurfaces and metamaterials for photovoltaic and photoelectrochemical water splitting applications
(WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2019)
In both photovoltaic (PV) and photoelectrochemical water splitting (PEC‐WS) solar conversion devices, the ultimate aim is to design highly efficient, low cost, and large‐scale compatible cells. To achieve this goal, the ...
Disordered nanohole patterns in metal-insulator multilayer for ultra-broadband light absorption: atomic layer deposition for lithography free highly repeatable large scale multilayer growth
(Nature Publishing Group, 2017)
In this paper, we demonstrate a facile, lithography free, and large scale compatible fabrication route to synthesize an ultra-broadband wide angle perfect absorber based on metal-insulator-metal-insulator (MIMI) stack ...
Experimental demonstration of the enhanced transmission through circular and rectangular sub-wavelength apertures using omega-like split-ring resonators
(Elsevier, 2013-02)
Enhanced transmission through circular and rectangular sub-wavelength apertures using omega-shaped split-ring resonator is
numerically and experimentally demonstrated at microwave frequencies. We report a more than ...
Nested metamaterials for wireless strain sensing
(IEEE, 2009-12-28)
We designed, fabricated, and characterized metamaterial-based RF-microelectromechanical system (RF-MEMS) strain sensors that incorporate multiple split ring resonators (SRRs) in a compact nested architecture to measure ...
