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: This paper proposes the orthogonal time frequency space-based code index modulation (OTFS-CIM) scheme, a novel wireless communication system that combines ...

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, ...
