Previous programmable metasurfaces integrated with diodes or varactors require external instructions for field programmable gate arrays (FPGAs), which usually rely on computer‐inputs or pre‐loaded algorithms. But the complicated external devices make the coding regulation process of the programmable metasurfaces cumbersome and difficult to use. To simplify the process and provide a new interaction...
Electromagnetic Manipulation and Encryption
To simplify the process and provide a new interaction manner, Lei Chen, Tie Jun Cui, and co‐workers propose a touch‐programmable metasurface (TPM) based on touch sensing modules to realize various electromagnetic (EM) manipulations and encryptions, in article number 2203871. Through the touch controls, TPM can achieve independent and direct manipulation...
