Hierarchical Reconfigurable Metasurface Based on Scenario‐Guided Functional Modules and Programmable Core

open access: yesAdvanced Science, EarlyView.
This paper proposes a hierarchical reconfigurable metasurface architecture (HRMA) to achieve comprehensive electromagnetic parameter modulation and on‐demand polymorphic function switching. The reconfigurable metasurface is divided into a programmable core (PC) and scenario‐guided functional modules (FMs), exhibiting significant flexibility and ...

Gate Enhancing Charge‐Spin Conversion in Organic Chiral Field Effect Transistors

open access: yesAdvanced Science, EarlyView.
Room‐temperature organic chiral multiferroic field effect transistors are demonstrated, enabling bidirectional control between spin and charge. Specifically, spin polarization affects the ferroelectric polarization, and ferroelectric polarization, in turn, can modulate spin polarization and spin‐dependent transport.

Large‐Aperture Polarization‐Independent Broadband Achromatic All‐Dielectric Metalens for Terahertz Focusing

open access: yesAdvanced Science, EarlyView.
A large‐aperture, high focusing efficiency and polarization‐independent THz single‐layer achromatic metalens is reported via discrete multi‐wavelength achromatic design and global optimization algorithm. The fabricated metalens exhibits a largest diameter of 2.21 cm, excellent achromatic performance, extremely high average focusing efficiency (> 46 ...
