Abstract: This paper analyzes the measured broadband signal echoes modulated by digital coding metasurfaces (DCMs) and concludes that the non-ideal broadband modulation results are related to the ...

Abstract: The recently proposed affine frequency division multiplexing (AFDM) is a new transmission waveform that has shown excellent performance in high-mobility environments, making it a sensible ...

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, ...
