Scattering from a random thin coating of nanoparticles: the Dirichlet case
Amandine Boucart, Sonia Fliss, Laure Giovangigli
We study the time-harmonic scattering by a heterogeneous object covered with a thin layer of randomly distributed sound-soft nanoparticles. The size of the particles, their distanc…
Probing the speckle to estimate the effective speed of sound, a first step towards quantitative ultrasound imaging
Josselin Garnier, Laure Giovangigli, Quentin Goepfert +1
In this paper, we present a mathematical model and analysis for a new experimental method [Bureau and al., arXiv:2409.13901, 2024] for effective sound velocity estimation in medica…
Scattered wavefield in the stochastic homogenization regime
Josselin Garnier, Laure Giovangigli, Quentin Goepfert +1
In the context of providing a mathematical framework for the propagation of ultrasound waves in a random multiscale medium, we consider the scattering of classical waves (modeled b…
Admittivity imaging from multi-frequency micro-electrical impedance tomography
Habib Ammari, Laure Giovangigli, Loc Hoang Nguyen +1
The aim of this paper is to propose an optimal control optimization algorithm for reconstructing admittivity distributions (i.e., both conductivity and permittivity) from multi-fre…
Spectroscopic imaging of a dilute cell suspension
Habib Ammari, Josselin Garnier, Laure Giovangigli +2
A rigorous homogenization theory is derived to describe the effective admittivity of cell suspensions. A new formula is reported for dilute cases that gives the frequency-dependent…
Mathematical modeling of fluorescence diffuse optical imaging of cell membrane potential changes
Habib Ammari, Josselin Garnier, Laure Giovangigli
The aim of this paper is to provide a mathematical model for spatial distribution of membrane electrical potential changes by fluorescence diffuse optical tomography. We derive the…
