Broad-band polarization-insensitive all-dielectric metalens enabled by intentional off-resonance waveguiding at mid-wave infrared
(American Institute of Physics, 2019)Metasurfaces are promising candidates to take the place of conventional optical components as they enable wavefront engineering at sub- and near-wavelength distances along both lateral and vertical directions. Plasmonic ... -
Disordered and densely packed ITO nanorods as an excellent lithography-free optical solar reflector metasurface
(American Chemical Society, 2019)Precise control and stabilization of the operating temperature environment of spacecraft and satellites during their life cycle is of paramount importance to increase device reliabilities and reduce the thermomechanical ... -
Disordered and densely packed ITO nanorods as an excellent lithography-free optical solar reflector metasurface for the radiative cooling of spacecraft
(SPIE, 2019)Optical Solar Reflectors (OSRs) form the physical interface between the spacecraft and space and they are essential for the stabilization and uniform distribution of temperature throughout the spacecraft. OSRs need to ... -
Metasurface microlens focal plane arrays and mirrors
(Bilkent University, 2017-02)Lenses, mirrors and focal plane arrays (FPAs) are among the key components a ecting the functionality, performance and cost of electro-optical (EO) systems. Conventional lenses rely on phase accumulation mechanism for ... -
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 ... -
Single and cascaded, magnetically controllable metasurfaces as terahertz filters
(Optical Society of America OSA, 2016)Transmission of a normally incident, linearly polarized, plane wave through either a single electrically thin metasurface comprising H-shaped subwavelength resonating elements made of magnetostatically controllable InAs ... -
Universally polarization-insensitive achromatic metasurfaces
(Bilkent University, 2019-07)Transparent optical components constitute the key elements of modern electro-optical systems including optical sensors, displays and imaging systems. The working principle of conventional transparent components rely on ...
