Advanced Science, Volume 13, Issue 12, 27 February 2026.Acoustic holograms act as key tools for information encryption, yet current schemes limit encryption dimensionality/security and require time‐consuming decryption. A compact device integrates multi‐dimensional cascaded acoustic holography with particle manipulation, employs extra secret keys, enables rapid decryption, and is validated via 1D/2D/3D ...

Water‐Wave Pancharatnam‐Berry Phase Induced by 4D Spin‐Orbit State Evolution
Advanced Science, Volume 13, Issue 2, 9 January 2026.The first observation of the Pancharatnam‐Berry (PB) phase in water waves is reported, revealing its extraordinary properties including unbounded phase values, spin‐momentum‐locked unidirectional channels, and a Poincaré hypersphere representation. These findings demonstrate the universality of the PB phase across different wave systems and in higher ...

A Comparison of Near-Field Acoustical Holography Methods Applied to Noise Source Identification [PDF]
, 2019 Near-Field Acoustical Holography (NAH) is an inverse process in which sound pressure measurements made in the near-field of an unknown sound source are used to reconstruct the sound field so that source distributions can be clearly identified.

Estimation of Sound Velocity Distribution Using Sectional Near-Field Acoustical Holography and Global Search [PDF]
, 2010 We propose a method of estimating sound velocity distribution by the combined use of near-field acoustical holography (NAH) and optimization. In this fundamental research, the sound velocity varies only in the z-axis, and the sound velocity is a ...
