Thermal Digital Imaging by Chirally Coded Metasurfaces
Laser & Photonics ReviewsAbstractChiral imaging, which utilizes chiral nanostructures to produce grayscale images, has attracted significant attention due to its potential for precise object and environmental perception. However, conventional chiral imaging techniques primarily rely on external light sources and other necessary optical components to create desired chiral ...

Controllable and Programmable Nonreciprocity Based on Detachable Digital Coding Metasurface
Advanced Optical Materials, 2019AbstractIn traditional nonreciprocial devices and nonreciprocial metamaterials, the nonreciprocity functions are fixed and noneditable. Here, a detachable digital coding metasurface is proposed integrated with power amplifiers to realize controllable and programmable nonreciprocity, in which a metasurface element embedded with two amplifiers is ...

Arbitrarily polarized retro-reflections by anisotropic digital coding metasurface
Journal of Physics D: Applied Physics, 2019Abstract We propose an anisotropic digital coding metasurface to realize arbitrarily polarized retro-reflections. With the theoretical support of generalized Snell’s laws, the proposed coding metasurface shows excellent performance of retro-reflections through reflection phase design.

Image wireless transmission based on microwave digital coding metasurfaces
Journal of the Optical Society of America BA 1-bit digital programmable reflective metasurface is proposed for controlling the far-field radiation pattern of reflected electromagnetic waves. By switching the on/off states of PIN diodes to correspond to digital “0” and “1” states, arranging different coding sequences enables flexible control of the electromagnetic waves. Based on the metasurface,
