Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes

Laser &Photonics Reviews, EarlyView.
This work proposes a novel strategy to achieve large Brillouin scattering with independent control of the optical and mechanical modes using subwavelength silicon membranes. We experimentally demonstrate remarkably high Brillouin gain, resulting in an on/off Stokes gain of 3 dB and anti‐Stokes loss of 4 dB in a 6 mm‐long waveguide with 35 mW of on‐chip

Low frequency acoustic properties of bilayer membrane acoustic metamaterial with magnetic oscillator [PDF]

, 2017
A bilayer membrane acoustic metamaterial was proposed to overcome the influence of the mass law on traditional acoustic materials and obtain a lightweight thin-layer structure that can effectively isolate low frequency noise. The finite element analysis (

Horizontal cloaking and vertical reflection by transformation acoustics

AIP Advances, 2013
This investigation shows that if an acoustic metamaterial bounded by an external rectangle and an internal circular cavity is properly engineered by a set of transformation equations that satisfy certain requirements, it can virtually cloak an object ...

Properties of Liquid Crystalline Elastomer Foams

Macromolecular Rapid Communications, EarlyView.
Controlled foaming of liquid crystalline elastomers (LCE) with expandable microspheres creates particle‐centred mesogenic interphases that enhance viscoelastic dissipation at low bubble fractions. Under impact, optimal damping shifts to moderate porosity, balancing interphase loss, bubble compression, compliance, and integrity.

Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method

Advanced Engineering Materials, Volume 28, Issue 16, 19 August 2026.
A novel compression–torsion metamaterial is engineered using inclined rods and symmetry breaking. To optimize its torsional performance, the golden section method is employed. The mechanical response of the metamaterial is validated through both numerical analysis and experimental validation.
