Diffractive Optics based on metamaterials
A new technology for producing flat optical components based on optical metasurfaces. These components can potentially serve high resolution imaging, spectrometry, light processing and beam shaping devices. The optical metasurfaces that we develop are composed of closely spaced optical nanoantennas which can be deposited on a wide variety of rigid and flexible surfaces. The engineered nanoantennas […] Read More >
Microelectromechanical Systems (Mems) Sensors and Actuators
Technology My research activity in the area of design and modeling of micro- and nanoelectromechanical systems (MEMS/NEMS) combines both theoretical and applied aspects and falls in several directions. The overall scope of the research is in the development of new approaches to actuation and sensing and their implementation in micro devices. In the realm of […] Read More >
Product Authentication using Nanoimprinting Lithography (NIL)
A unique Nano Imprinting Lithography (NIL) technology, based on a polymeric replication method, to battle counterfeiting • Extremely difficult to copy or forge • Inexpensive implementation (tag printing) Tag printing: Imprint on the brand product a set of nanometer scale patterns that are invisible to the naked eye (and most microscopes) Authentication: “Read” and analyze the tag […] Read More >
Cost-Effective Distributed Acoustic Sensing
Optical fibers are widely known in their ability to transfer huge amounts of data efficiently and cost-effectively. As the backbone of our communications networks, optical fibers are everywhere: underground or aerial in our streets, underwater in the oceans, along highways, railways, pipelines, power lines and fences, in campuses and in data centers. Optical fibers are […] Read More >
Hyperspectral Imaging Method and System using a Flock of Small Satellites
Remote sensing by satellites is the most major tool in earth observation. In recent decades, governments and the private sector have invested billions in earth surveillance satellite missions. Environmental and agricultural surveillance requires multi-spectral visible, NIR, SWIR, and thermal imagery. Traditionally imagery satellites equipped with a bulky high-resolution camera resulted in heavy and expensive satellite […] Read More >
Error Correction Code Transformer
Error correction code is a major part of the communication physical layer, ensuring the reliable transfer of data over noisy channels. Recently, neural decoders were shown to outperform classical decoding techniques. However, the existing neural approaches present strong overfitting due to the exponential training complexity, or a restrictive inductive bias due to reliance on Belief […] Read More >
A Lensless Polarization Camera
Polarization imaging is a technique that creates a pixel-map of the polarization state in a scene. Although invisible to the human eye (and for most conventional cameras), polarization can assist various sensing and computer vision tasks. Existing polarization cameras acquire the additional modality using either spatial or temporal multiplexing, which increases the camera volume, weight, […] Read More >
LWIR / FIR / THz Detectors and Sources For High Sensitivity Remote Sensing
MIR-THz Detectors and Sources For High Sensitivity Remote Sensing The discoveries of novel materials and physical phenomena continuously drive technological advancements and their applications. So is the case for MIR-THz optoelectronics, operating roughly in the frequency range of f≈0.5-35THz. In this spectral range radiation penetrates through opaque materials without the risk of ionization, making MIR-THz […] Read More >
Broad-Bandwidth, Long-Haul, Underwater Fiber-Optic Sensing System
An optical fiber can be described as a glass pipeline which can guide light over great distances with very little loss. In addition to being the central communication channel of the information era, it has another very interesting application. This application is called distributed sensing. By launching into the fiber specially designed pulse sequences of […] Read More >
High Resolution Robotic Fingers
Traditional robotic hands have a complex structure with many degrees-of-freedom, while they can be large, fragile and with high cost. In addition, they usually cannot perform gentle and precise in-hand manipulation that is required in, for example, medical procedures and assembly of small components. We propose a sophisticated mechanism that enables to augment the capabilities […] Read More >
