Abstract: Abstract Previously, a two-dimensional (2-D) analytical model for interpreting the modulation mechanism of a “breathing” crack on guided ultrasonic waves (GUWs) is developed [1]. Based on the theory of wave propagation in three-dimensional (3-D) waveguides… read more here.

Abstract: When a torus oscillates horizontally in a linearly stratified fluid, the wave rays form a double cone, one upward and one downward, with two focal points where the wave amplitude has a maximum due to… read more here.
