Active Convolved Illumination with Deep Transfer Learning for Complex Beam Transmission through Atmospheric Turbulence
Adrian A. Moazzam, Anindya Ghoshroy, Breeanne Heusdens +2
Atmospheric turbulence imposes a fundamental limitation across a broad range of applications, including optical imaging, remote sensing, and free-space optical communication. Recen…
Enhanced superlens imaging with loss-compensating hyperbolic near-field spatial filter
Anindya Ghoshroy, Wyatt Adams, Xu Zhang +1
Recently a coherent optical process called plasmon injection () scheme, which employs an auxiliary source, has been introduced as a new technique to compensate losses in metamat…
Hyperbolic metamaterial as a tunable near-field spatial filter for the implementation of the active plasmon injection loss compensation scheme
Anindya Ghoshroy, Xu Zhang, Wyatt Adams +1
We present how to physically realize the auxiliary source described in the recently introduced active plasmon injection loss compensation scheme for enhanced near-field superlensin…
Perfect compensation of absorption in metamaterials for diffraction-unlimited imaging
Wyatt Adams, Durdu Ö. Güney
To overcome the resolution limit of conventional optics, near field imaging techniques using a negative index flat lens (NIFL) have been previously developed that amplify the evane…
Enhancing the resolution of hyperlens by the compensation of losses without gain media
Xu Zhang, Wyatt Adams, Mehdi Sadatgol +1
We present a method to improve the resolution of available hyperlenses in the literature. In this method, we combine the operation of hyperlens with the recently proposed plasmon i…
Bringing the 'perfect lens' into focus by near-perfect compensation of losses without gain media
Wyatt Adams, Mehdi Sadatgol, Xu Zhang +1
In this paper, the optical properties and imaging performance of a non-ideal Pendry's negative index flat lens with a practical value for loss are studied. Analytical calculations…
Magneto-optical metamaterial
Mehdi Sadatgol, Mahfuzur Rahman, Ebrahim Forati +2
We propose a new class of metamaterials called magneto-optical metamaterials that offer enhanced angle of rotation in polarization compared to bulk magneto-optical materials. In th…
Plasmon Injection to Compensate and Control Losses in Negative Index Metamaterials
Mehdi Sadatgol, Şahin K. Özdemir, Lan Yang +1
Metamaterials have introduced a whole new world of unusual materials with functionalities that cannot be attained in naturally occurring material systems by mimicking and controlli…
Exchanging Ohmic Losses in Metamaterial Absorbers with Useful Optical Absorption for Photovoltaics
Ankit Vora, Jephias Gwamuri, Nezih Pala +3
Using metamaterial absorbers, we have shown that metallic layers in the absorbers do not necessarily constitute undesired resistive heating problem for photovoltaics. Tailoring the…
Dual-band, double-negative, polarization-independent metamaterial for the visible spectrum
Muhammad I. Aslam, Durdu Ö. Güney
We present the first dual-band negative index metamaterial that operates in the visible spectrum. The optimized four-functional-layer metamaterial structure exhibits the first doub…
Surface plasmon driven scalable low-loss negative-index metamaterials at visible spectrum
Muhammad I. Aslam, Durdu Ö. Güney
We demonstrate that surface plasmons of a thin metal film interacting with a periodic array of nano-structures around it can be utilized to make bulk negative index metamaterials a…
Intra-connected three-dimensionally isotropic bulk negative index photonic metamaterial
Durdu O. Guney, Thomas Koschny, Costas M. Soukoulis
Isotropic negative index metamaterials (NIMs) are highly desired, particularly for the realization of ultra-high resolution lenses. However, existing isotropic NIMs function only t…
