Stylolites complicate sound wave propagation in sedimentary rock samples, affecting lab-scale monitoring
Stylolites—irregular seams that occur in limestone—have been found to affect how acoustic waves move through rock samples. Laboratory-based insights from KAUST researchers offer an improved ...
The top layer represents the location of the sound source and the path of sound propagation (A). The bottom layers represent convergence zones with different sound propagation paths (B-F). Sound waves ...
SIAM Journal on Applied Mathematics, Vol. 79, No. 6 (2019), pp. 2663-2687 (25 pages) We analyze sound propagation in a waveguide filled with a random medium modeled by small-amplitude spatial and ...
In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...
Time-harmonic acoustic wave propagation is considered in the presence of a spatially and temporally randomly perturbed parabolic profile. A scaling based on typical ocean environments is introduced. A ...
Scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne have developed a device that directs sound waves in one direction without wasting energy. This breakthrough sound wave ...
