Invisibility on demand based on a generalized Hilbert transform 

Hayran, Zeki; Herrero, Ramon; Botey, Muriel M.; Kurt, Hamza; Staliunas, Kestutis (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 ...

Disturbance/Uncertainty Estimator Based Robust Control of Nonminimum Phase Systems 

Kürkçü, B.; Kasnakoğlu, Coşku; Efe, M.O. (Institute of Electrical and Electronics Engineers Inc., 2018-08)
An open problem in disturbance/uncertainty estimator based control is to obtain explicit mathematical expressions for robust stability, performance, and bandwidth requirement. This paper offers a path based on H-infinity ...

Full utilization of semi-Dirac cones in photonics 

Kurt, Hamza; Yasa, Utku G.; Turduev, Mirbek; Giden, İbrahim Halil (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. ...

Genetically optimized design of ultra-compact and highly efficient waveguide crossing, optical attenuator and reflector 

Şahin, Umut; Bor, Emre; Kurt, Hamza; Turduev, Mirbek (IEEE Computer Society, 2019)
In this study, we present the design of ultra-compact and highly efficient photonic integrated devices by applying a meta-heuristic approach. Here, we integrated the three-dimensional finite-difference time-domain method ...

3D imaging for ground-penetrating radars via dictionarydimension reduction 

Duman, Muhammed; Gürbüz, Ali Cafer (TÜBİTAK, 2015)
Ground-penetrating radar (GPR) has been widely used in detecting or imaging subsurface targets. In many applications such as archaeology, utility imaging, or landmine detection, three-dimensional (3D) images of the subsurface ...

Angular filtering by Bragg photonic microstructures fabricated by physical vapour deposition 

Grineviciute, Lina; Babayigit, Ceren; Gailevicius, Darius; Bor, Emre; Turduev, Mirbek; Purlys, Vytautas; Tolenis, Tomas; Kurt, Hamza; Staliunas, Kestutis ( Elsevier B.V., 2019)
We propose and experimentally demonstrate spatial filtering by photonic crystals in a Bragg configuration. Compared to the Laue configuration, where spatial filtering was already demonstrated before, the Bragg configuration ...

Thermally Tuning Infrared Light Scattering Using Planar Layered Thin Films and Space Gradient Metasurface 

Koçer, Hasan; Özer, Ahmet; Bütün, Serkan; Wang, Kevin; Wu, Junqiao; Kurt, Hamza; Aydın, Koray (Institute of Electrical and Electronics Engineers Inc., 2019-05)
We experimentally demonstrate a tunable planar layered thin film (PLTF) structure operating at the short-wavelength infrared spectrum by employing the phase transition of vanadium dioxide through thermal stimulus. We obtain ...

Broadband asymmetric light transmission based on all-dielectric metasurfaces in the visible spectrum 

Özer, Ahmet; Yılmaz, Nazmi; Koçer, Hasan; Kurt, Hamza (IOP PUBLISHING LTD, 2019-05)
An asymmetric transmission device composed of all dielectric phase gradient metasurfaces on the dielectric substrate in the visible wavelengths is proposed and designed. In order to verify its operation principle and ...

An Optical Sensor Design Using Surface Modes of Low-Symmetric Photonic Crystals 

Erim, Nur; Erim, Muhammed Necip; Kurt, Hamza (Institute of Electrical and Electronics Engineers Inc., 2019)
In this paper, an optical sensor design is proposed with low-symmetric photonic crystals that support surface modes. In order to obtain low symmetry, rotational symmetry is broken within the unit cell size while translational ...

Spectral splitting for an InGaP/GaAs parallel junction solar cell 

Erim, Muhammed Necip; Erim, Nur; Kurt, Hamza ( OSA - The Optical Society, 2019)
In this paper, a design of a diffractive optical element to split the solar spectrum into two separate parts for a laterally arrayed InGaP/GaAs solar cell is presented. Optical simulation is done by using the three-dimensional ...
