Broadband low-frequency sound absorption in open tunnels with deep sub-wavelength Mie resonators
Frontiers in Physics, 2022 We report both experimentally and numerically that near-perfect absorption of low-frequency sound is realized in an open tunnel embedded with two deep sub-wavelength (0.085 λ) Mie resonators. The resonators are composed of a multiple-cavity structure and

Conoids and Hyperbolic Paraboloids in Le Corbusier’s Philips Pavilion [PDF]
, 2015 The Philips Pavilion at the Brussels World Fair is the first of Le Corbusier’s architectural works to connect the evolution of his mathematical thought on harmonic series and modular coordination with the idea of three-dimensional continuity.

Acoustic Kerr nonlinearity of wave propagation in a planar nanoelectromechanical waveguide [PDF]
Phys. Rev. Applied 13, 014056 (2020), 2019 Nonlinearity is the key to introducing novel concepts in various technologies utilizing traveling waves. In contrast to the field of optics, where highly functional devices have been developed using optical Kerr nonlinearity, such a nonlinear effect in acoustic devices has yet to be fully exploited.

Experimental demonstration of three-dimensional broadband underwater acoustic carpet cloak [PDF]
, 2018 We present the design, architecture and detailed performance of a three-dimensional (3D) underwater acoustic carpet cloak (UACC). The proposed system of the 3D UACC is an octahedral pyramid which is composed of periodical steel strips. This underwater acoustic device, placed over the target to hide, is able to manipulate the scattered wavefront to ...
