Signatures of Emerging Subsurface Structures in Acoustic Power Maps
, 2010 We show that under certain conditions, subsurface structures in the solar interior can alter the average acoustic power observed at the photosphere above them.

Wave modes excited by photospheric p-modes and mode conversion in a multi-loop system
, 2019 Context. Waves are ubiquitous in the solar corona and there are indications that they are excited by photospheric p-modes. However, it is unclear how p-modes in coronal loops are converted to sausage modes and transverse (kink) modes, which are observed ...

Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry
Advanced Materials Interfaces, EarlyView.We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.

Hybrid Magnetoactive Soft Elastomers: Material Development Toward Application in Diaphragm Pumps
Advanced Materials Technologies, EarlyView.Hybrid magnetoactive soft elastomeric membranes are developed by combining two different types of magnetic particles. The membranes exhibit distinct mechanical, magnetic and thermal properties owing to the unique characteristics of the two magnetic particles.

Ductility Tuning via Cluster Network Characteristics of Porous Components
Advanced Materials Technologies, EarlyView.Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by

Air-ground interface: Surface waves, surface impedance and acoustic-to-seismic coupling coefficient [PDF]
In atmospheric acoustics, the subject of surface waves has been an area of discussion for many years. The existence of an acoustic surface wave is now well established theoretically.
