AI Technical Summary

Technical Problem

Existing acoustic metamaterials and electromagnetic metasurfaces are difficult to coordinately control acoustic and electromagnetic beams in the same structure, and there are problems of unexpected mutual interference and reduced control accuracy.

Method used

A dual-field beam synchronous control device using reconfigurable acoustic metamaterials and electromagnetic metasurfaces is employed. The acoustic cavity and electromagnetic coupling structure are synchronously driven by a single mechanical rotating shaft. An isolation layer is used to physically isolate the acoustic and electromagnetic control regions, thereby achieving continuous reconfigurable control of the dual-field beams.

Benefits of technology

It achieves synchronous and stable adjustment of acoustic and electromagnetic beams, reduces non-target coupling and interference, improves control accuracy and system integration, and adapts to complex application environments.

Abstract

This invention discloses a reconfigurable acoustic metamaterial and electromagnetic metasurface dual-field beam synchronous control device, comprising several synchronous control units. Each synchronous control unit includes a stator end cover, a rotor end cover, a hollow rotating rotor, and a stator shell. A circular groove is formed inside the stator shell, and an acoustic inlet and an acoustic outlet are provided on the shell. The hollow rotating rotor has a cylindrical structure and is coaxially disposed within the circular groove of the stator shell, with a first opening and a second opening symmetrically formed on its sidewalls. The first and second openings selectively communicate with the acoustic inlet and acoustic outlet, respectively. By rotating the rotor, the alignment between the openings is changed, thereby continuously adjusting the effective flow area of ​​the acoustic channel and achieving control of the acoustic resonant frequency.
