Simplified radar architecture based on information metasurface [PDF]

Nature Communications
Modern radar typically employs a chain radio-frequency (RF)-digital architecture, imposing high costs, substantial hardware burdens, and integration challenges. Here, we propose a simplified radar architecture based on space-time-coding (STC) information

Dual-band and dual-polarization coding metasurface for independent controls of phases and amplitudes with cross-polarized transmissions in two bands

Results in Physics
An ideal metasurface design encompasses the control of all the degrees of freedom of electromagnetic (EM) waves. Here, we present a digital coding metasurface optimized for dual-band operations (in K and Ka band) for orthogonal polarizations.

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 ...

Flexibly control of vortex beams based on all-dielectric Pancharatnam-Berry phase transmission encoding metamaterials

Results in Physics, 2023
Because the ohmic loss of metal materials affects the transmission efficiency of metasurface, we design a transmission-type all-dielectric coded metasurface element structure based on the principle of Pancharatnam-Berry geometric phase.
