(2014-04-14)In this study, silver incorporated indium sulfide (In2S3) thin films have been deposited on soda lime glass via spray pyrolysis technique. Structural and electrical properties have been tailored by adding controlled amount ...
-
(ESG, 2014-06)For the first time with this study, membranes from directly copolymerized disulfonated poly(arylene ether sulfone) (BPSH 35) were utilized to replace NafionTM in vanadium redox flow batteries (VRFB). Direct copolymerization ...
-
(Elsevier Ltd., 2018-05-05)Novel nanoporous catalysts from selective dissolution of alloys have been prepared for fast hydrogen generation from chemical hydrides. Pt and Ru have been used as precious metals in the alloys, while the nonprecious metal ...

(Royal Society of Chemistry, 2018-07-02)We employed polymer functionalized silica gel as an adsorbent for the removal of Cr(vi) from water. The chains of 2-aminoethyl methacrylate hydrochloride (AEMA·HCl) polymer were grown from the surface of silica gel via ...
-
(American Physical Society, 2018-12-10)In this paper, we present the numerical and experimental demonstration of asymmetric light transmission by a compact photonic crystal (PC) structure, which sustains semi-Dirac cone dispersion. The semi-Dirac point is ...
-
(Optical Society of America, 2018-12-01)In this Letter, the design of a directional optical cloaking by a genetic algorithm is proposed and realized experimentally. A three-dimensional finite-difference time-domain method is combined with the genetic optimization ...
-
(OSA - The Optical Society, 2018-10-29)Recently, different nanophotonic computational design methods based on optimization algorithms have been proposed which revolutionized the conventional design techniques of photonic integrated devices. The intelligently ...
-
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2018-10-01)We propose an asymmetric to quasisymmetric behavioral tunability of a structured filter operating in the mid-infrared (IR) spectral region, where the atmospheric transparency is high. The structure is designed through ...
-
(American Institute of Physics Inc., 2018-09-24)We propose compact S-vector superprism providing broadband wavelength sensitivity within a/λ = 0.610-0.635, where "a" is the lattice constant, λ is the incident wavelength, and S denotes the Poynting vector. The reported ...
-
(OSA - The Optical Society, 2018-09-15)Beam splitters play important roles in several optical applications, such as interferometers, spectroscopy, and optical communications. In this study, we propose and numerically examine polarization-insensitive beam splitters ...
-
(OSA - The Optical Society, 2018-09-01)In modern optical applications, it has become an important need to flow light unidirectionally. An optical diode realizes this task as an electrical counterpart manipulates the flow of electrons in semiconductor materials. ...

Ultracompact Photonic Structure Design for Strong Light Confinement and Coupling Into Nanowaveguide (Institute of Electrical and Electronics Engineers Inc., 2018-07-15)Different optimization algorithms have recently been utilized to design and improve the performance of many nanophotonic structures. We present the design of a compact photonic structure by an approach based on machine ...
-
(American Physical Society, 2018-07-12)We propose a feasible invisibility approach to suppress the scattering of waves from or to given directions and for particular frequencies, i.e., invisibility on demand. We derive a generalized Hilbert transform for a ...
-
(OSA - The Optical Society, 2018-06-01)We propose and demonstrate reduced symmetry photonic surfaces providing highly controlled Bloch wave propagation. The backward and dual directional propagations have been observed in the proposed low-symmetric periodic ...
-
(OSA - The Optical Society, 2018-06-01)In this study, we report a low-symmetric photonic crystal (PhC) structure that exhibits high coupling efficiency in a broadband frequency range with a tilted self-collimating capability. First, the analytical approach is ...
-
(American Physical Society, 2018-05-16)In this study, realization and applications of anisotropic zero-refractive-index materials are proposed by exposing the unit cells of photonic crystals that exhibit Dirac-like cone dispersion to rotational symmetry reduction. ...
-
(American Chemical Society, 2018-05-16)A general procedure to design objects that are intrinsically invisible (without the necessity of an external cloak) has not been demonstrated so far. Here we propose a flexible method to design such self-cloaked objects ...
-
(American Physical Society, 2018-03-15)We propose an approach based on a local Hilbert transform to design non-Hermitian potentials generating arbitrary vector fields of directionality, p→(r→), with desired shapes and topologies. We derive a local Hilbert ...
-
(IOP Publishing Ltd., 2018-01-17)Direction-dependent light transmission is a remarkable phenomenon owing to its great potential to be used in optical communication processing systems such as optical diodes, isolators and rectifiers. All these applications ...
-
(American Physical Society, 2018-01-05)The existence and exact form of the continuum expression of the discrete nonlogarithmic q-entropy is an important open problem in generalized thermostatistics, since its possible lack implies that nonlogarithmic qentropy ...
