Acoustic resonance spectra of a finite cylindrical shell [PDF]
The Journal of the Acoustical Society of America, 1988 Previous studies have explained acoustic scattering from an infinite cylinder or a sphere. The scattering depends strongly on resonances that are related to the propagation of circumferential waves when the acoustic axis is perpendicular to the cylinder axis or the propagation of guided waves when the insonification is oblique.

Hawking radiation in dispersive media [PDF]
, 2011 Hawking radiation, despite its presence in theoretical physics for over thirty years, remains elusive and undetected. It also suffers, in its original context of gravitational black holes, from conceptual difficulties.

Advanced Materials, EarlyView.Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Spectra of Interacting Acoustical Waves with a Turbulent Wake [PDF]
The Journal of the Acoustical Society of America, 1969 The state of a compressible fluid is completely prescribed by its velocity, density, pressure, and temperature fields. When the compressible fluid is in a turbulent flow, all these quantities fluctuate in a random manner. Space-time Fourier transforms are used to show that these state variables separate into two physically distinct groups, one ...
