Breaking Reciprocity with Space‐Time‐Coding Digital Metasurfaces [PDF]
Advanced Materials, 2019 AbstractMetasurfaces are artificially engineered ultrathin structures that can finely tailor and control electromagnetic wavefronts. There is currently a strong interest in exploring their capability to lift some fundamental limitations dictated by Lorentz reciprocity, which have strong implications in communication, heat management, and energy ...

Space-time-coding digital metasurfaces [PDF]
Nature Communications, 2018 AbstractThe recently proposed digital coding metasurfaces make it possible to control electromagnetic (EM) waves in real time, and allow the implementation of many different functionalities in a programmable way. However, current configurations are only space-encoded, and do not exploit the temporal dimension. Here, we propose a general theory of space-
