Witryna21 kwi 2015 · We propose and theoretically explore terahertz amplification, based on stimulated generation of plasmons in graphene asymmetric hyperbolic metamaterials (AHMM), strongly coupled to terahertz radiation. In contrast to the terahertz amplification in resonant nanocavities, AHMM provides a wide-band THz amplification without any … Witryna3 mar 2024 · Metamaterial hardware has enabled alternative low-cost aperture architectures, referred to as “meta-imagers.” These coded metamaterial apertures multiplex scene information across diverse measurement modes, offered by the metamaterial's degrees of freedom, onto a single (or few) detector(s); however, …
Witryna2 mar 2024 · Over the past 5 years, digital coding and programmable metamaterials have been developed rapidly since their first exhibition in 2014. The iconic feature of the digital coding metamaterial is using digital codes like “0” and “1” to represent the distinct electromagnetic (EM) responses. This seemingly trivial progress has successfully …
