Geometrical-acoustics approach to the description of localized vibrational modes of an elastic solid wedge [PDF]
, 1990 A geometrical-acoustics theory is derived for localized vibrational modes of an elastic solid wedge, or "wedge acousiic waves." Simple analytical expressions are derived for the phase velocities and displacement amplitudes of antisymmetric modes of an ...

Acoustic geometric-phase meta-array [PDF]
New Journal of Physics, 2021 Abstract Metasurfaces based on geometric phase acquired from the conversion of the optical spin states provide a robust control over the wavefront of light, and have been widely employed for construction of various types of functional metasurface devices.

Numerical geometric acoustics [PDF]
The Journal of the Acoustical Society of America, 2020 We present a new approach to offline room acoustic modeling and simulation based on solving the eikonal equation, a nonlinear partial differential equation describing the arrival times of a high-frequency wavefront. We call the approach numerical geometric acoustics, since it combines some of the advantages of both numerical acoustics, where the ...

Experimental verification of the acoustic geometric phase
Applied Physics Letters, 2022 Optical geometric phase encoded by in-plane spatial orientation of microstructures has promoted the rapid development of numerous functional meta-devices. However, pushing the concept of the geometric phase toward the acoustic community still faces challenges.

Comparative Visualization for Wave-based and Geometric Acoustics [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2006 We present a comparative visualization of the acoustic simulation results obtained by two different approaches that were combined into a single simulation algorithm. The first method solves the wave equation on a volume grid based on finite elements.
