Resonant Modal Approximation of Time-Domain Elastic Scattering from Nano-Bubbles in Elastic Materials
Resonant Modal Approximation of Time-Domain Elastic Scattering from Nano-Bubbles in Elastic Materials
.This paper is devoted to establishing the resonant modal expansion of the low-frequency part of the scattered field for acoustic bubbles embedded in elastic materials. Due to the nanobubble with damping, the Minnaert resonance can be induced at certain discrete resonant frequencies, which forms the fundamental basis of effectively constructing …
