TetraScatt model: Born approximation for the estimation of acoustic dispersion of fluid-like objects of arbitrary geometries
Edmundo F. Lavia, Guadalupe Cascallares, Juan D. Gonzalez
Modelling the acoustic scattering response due to penetrable objects of arbitrary shapes, such as those of many marine organisms, can be computationally intensive, often requiring…
A 3D acoustic propagation model for shallow waters based on an indirect Boundary Element Method
Edmundo F. Lavia, Juan D. Gonzalez, Silvia Blanc
The purpose of this work is twofold: (a) To present the theoretical formulation of a 3D acoustic propagation model based on a Boundary Element Method (BEM), which uses a half-space…
Acoustic scattering by two fluid confocal prolate spheroids
Edmundo Federico Lavia
The exact spheroidal-function series solution for the time-harmonic acoustic scattering of a plane wave by two fluid confocal prolate spheroids is developed and a numerical impleme…
Boundary-element method to analyze acoustic scattering from a coupled swimbladder-fish body configuration
Juan D. Gonzalez, Edmundo F. Lavia, Silvia Blanc +2
A model for computing acoustic scattering by a swimbladdered fish with coupling to surrounding fish tissue that is assumed to behave as a homogeneous fluid, is presented. Mathemati…
Modelling High-Frequency Backscattering from a Mesh of Curved Surfaces Using Kirchhoff Approximation
Edmundo Lavia, Juan D. Gonzalez, Silvia Blanc
The Kirchhoff approximation (K-A) to calculate the acoustic backscattering of a complex structure can be evaluated using a discretized version of its surface (i.e. a $\textit{mesh}…
A Computational Method to Calculate the Exact Solution for Acoustic Scattering by Fluid Spheroids
Juan D. González, Edmundo F. Lavia, Silvia Blanc
The problem of scattering of harmonic plane acoustic waves by fluid spheroids (prolate and oblate) is addressed from an analytical approach. Mathematically, it consists in solving…
