Abstract: Metasurfaces can alter radar echo characteristics by dynamically modulating the phase of incident electromagnetic waves, thereby degrading radar signal processing performance. Recovering the ...

Abstract: Utilizing periodic phase modulation (PPM) can shift the echo spectrum, affecting matched filtering (MF) processing, leading to time delay shift or amplitude attenuation. The prior works on ...

SAN FRANCISCO, Dec 11 (Reuters) - A U.S. lawmaker has proposed phasing out Chinese-made sensors in self-driving cars and critical infrastructure amid warnings they could be hacked and disabled from ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...
