Since the concepts of digital coding metasurface and programmable metasurface were put forward in 2014, the physical world of electromagnetics has been closely connected to the digital world of ...

Architecture of the proposed compact twisted meta-device for frequency-reconfigurable holography. The meta-device integrates cascaded radiation-type metasurfaces (RA-M) with phase-only metasurfaces (P ...

Radio spectrum is pricey. Operators drop billions at auction to lock down licensed frequency bands, and every single frequency counts. Dynamic Spectrum Sharing (DSS) was built to address exactly this, ...

A talk, The Unreasonable Effectiveness of the Fourier Transform, was presented by [Joshua Wise] at Teardown 2025 in June last year. Click-through for the notes or check out the video below the break ...

Announcing a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250229 .Programmable metasurface (PM), also termed as ...
