Active control of electroacoustic resonators in the audible regime: control strategies and airborne applications

Опубликована: Апрель 7, 2025

Abstract Passive sound mitigation techniques have garnered attention whether for absorption, isolation, reverberation or new wave phenomena observation. In parallel, a wide range of research has been devoted to active control strategies, which complement passive techniques, particularly low-frequency. We review the main related with airborne acoustic in audible regime, emphasizing electrodynamic loudspeakers and piezo-diaphragms, their applications. conclude by discussing perspectives this evolving field.

Perspective on nonvolatile magnon-signal storage and in-memory computation for low-power consuming magnonics

Applied Physics Letters, Год журнала: 2025, Номер 126(16)

Опубликована: Апрель 21, 2025

Magnons are the quanta of spin waves and transport angular momenta through magnetically ordered materials. They can be used to distribute control on-chip GHz signals without charge flow, thereby avoiding Joule heating. Beyond multiplexed signal processing, filtering, Boolean logic, they allow for hardware implementation neural networks exploiting cascaded magnon scattering on nanoscale. A game-changing boost is expected if nonvolatile magnon-signal storage in-memory computation schemes become realistic. We outline recent progress in experimental research micromagnetic modeling toward these goals before sketching remaining challenges.

By harnessing multiple dimensions of light to implement mathematical functions, structured optical materials introduce a twist in the paradigm informatics, shifting from "displaying with light" "computing light". One vital subset operators is binary operators, whose output depends on two inputs, such as Boolean logic. Herein, we propose and demonstrate an operator based thermally controllable chiral nanostructures. engineering anisotropic materials, determined by interplay between inputs; furthermore, accompanying Pancharatnam-Berry phase unlocks additional computing functionalities. The customized modulation orbital angular momentum intensity distribution enables operations integers images. tunable operating spectrum spans ultrawide range over 1600 nm visible near-infrared region. This study reveals new opportunities for soft matter may facilitate diverse applications machine vision artificial intelligence.
