Broadband Radar Invisibility with Time-Dependent Metasurfaces
In the modern aerospace and defense sectors, stealth technology is crucial for aircraft survivability. Current methods primarily rely on shaping, radar-absorbing coatings, and electronic jamming to evade detection. However, these techniques face substantial limitations: they are often narrowband, bulky, and vulnerable to sophisticated radar systems that can distinguish stealth aircraft, especially when targets are moving.

DifuzCam: Replacing Camera Lens with a Mask and a Diffusion Model
DifuzCam represents a novel approach of flat lensless camera imaging. By eliminating traditional lenses and instead using a diffuser near the sensor, the camera size, weight and cost are drastically reduced. However, reconstructing high-quality images from the raw sensor data of such cameras is an ongoing challenge. Our invention proposes a solution by leveraging a […] Read More >
Calibration of Fiber Optic Sensor Underground
The precise geolocation of underground fiber optic telecom cables is crucial for operator maintenance, to avoid construction-related damage, and to minimize costs during network upgrades. Our innovative calibration technology provides non-instrusive high-accuracy localization of subsurface fiber optic cables, using only video inputs and ambient urban under any noise conditions. In addition, the same data are […] Read More >
Traffic Monitoring Using Fiber Optic Sensor
The rapid development of smart cities and their infrastructure requires innovative solutions for traffic monitoring. Fiber optic sensors offer a high-precision, reliable, anonymous, and cost-effective method for real-time traffic data acquisition and analysis. We have developed an AI-based technology, using fiber-optic sensors for comprehensive traffic monitoring systems, enhancing traffic management and safety. UNMET NEED Current […] Read More >
Image Processing – Non-Local Image Dehazing
Prof. Shai Avidan Tel Aviv University, School of Electrical Engineering Haze limits visibility and reduces image contrast in outdoor images. The degradation is different for every pixel and depends on the distance of the scene point from the camera. This dependency is expressed in the transmission coefficients, that control the scene attenuation and amount of […] Read More >
Anomaly Detection in Video
We propose a new method for anomaly detection of human actions. Our method works directly on human pose graphs that can be computed from an input video sequence. This makes the analysis independent of nuisance parameters such as viewpoint or illumination. We map these graphs to a latent space and cluster them. Each action is […] Read More >
A Fully Integrated Chip Scale Dielectric Resonance Antenna
Due to limited voltage supplies in scaled CMOS and the lower amplitude of harmonic generation at frequencies above transistors’ fmax, the radiated power out of a single element around 300GHz is limited to 0.5mW. Generating more power by combining signals from several locked sources on chip to the same on-chip antenna is not efficient due […] Read More >
Partially coherent radar for car applications
Many different approaches for mapping nearby moving objects are under fast development nowadays due to a number of highly important emerging applications, including autonomous cars and many others. The majority of existent proposals for solving the problem are based on optical imaging with subsequent post processing. While this concept already delivered impressive working prototypes (e.g. […] Read More >
Passive communications with time-varying metamaterials
The coming years will see a revolution by connecting everything to anyone, and RFID and similar technologies, will lead this 300B$ USD industry and 50B connected devices. Examining existing RFID standards suggests that the leading standard, called EPC Gen 2, is a standard in the 900MHz frequency which allows hundreds of tags to be read […] Read More >
A Software Only Anti-Spoofing Defense System for In-Car CAN Bus Networks
Modern cars have multiple dedicated computers under the hood called “electronic control units” (ECUs). These ECUs control many aspects of the car’s operation and are connected to each other in a network that typically uses the CAN bus protocol, which bus is a serial protocol with no security components. Replacing CAN bus with another technology […] Read More >
