Coding Metasurface for Talbot Sound Amplification
Physical Review Applied, 2020The Talbot effect has found profound applications in a wide variety of research fields, facilitating the development of sensing, imaging, and lithography, among others. Taking advantage of the flexibilities offered by the bidimensional Talbot effect, we propose and experimentally demonstrate a 2-bit coding acoustic metasurface lens.

Bispectral Circular Dichroic Coding Metasurfaces
Annalen der Physik, 2020AbstractThe frequency‐dependent circular dichroism is proposed to extend the wave manipulating capability of coding metasurfaces. As a proof of concept, the bispectral circular dichroic coding metasurfaces (CDCMs) are realized using circular dichroism resonators (CDRs) implemented via introducing loss resistors into the circular polarization conversion

A Coding Diffuse Metasurface for RCS Reduction
IEEE Antennas and Wireless Propagation Letters, 2017In this letter, a coding diffuse metasurface for radar cross section (RCS) reduction is designed, simulated, and measured. First, two kinds of artificial magnetic conductor (AMC) unit cell are analyzed, and 5 × 5 AMC unit cells construct metamaterials block.

Coding Programmable Metasurfaces Based on Deep Learning Techniques
IEEE Journal on Emerging and Selected Topics in Circuits and Systems, 2020Programmable metasurfaces have recently been proposed to dynamically manipulate electromagnetic (EM) waves in both temporal and spatial dimensions. With active components integrated into unit cells of the metasurface, states of the unit cells can be adjusted by digital codes.

Coding metasurfaces for beams manipulation
Codage par métasurfaces pour la manipulation de faisceaux Dans cette thèse, nous développons une méthode pour l'implémentation de metasurfaces à forte diffusion à l'aide de métasurfaces à codage aléatoire 1-bit. De telles metasurfaces permettent de réduire la Surface Équivalente Radar (SER) dans une large bande de fréquences sans ...openaire +1 more source
