The inverse source problem for the wave equation revisited: A new approach

M Sini, H Wang - SIAM Journal on Mathematical Analysis, 2022 - SIAM
The inverse problem of reconstructing a source term from boundary measurements, for the
wave equation, is revisited. We propose a novel approach to recover the unknown source …

Dispersive Effective Model in the Time-Domain for Acoustic Waves Propagating in Bubbly Media

A Mukherjee, M Sini - arxiv preprint arxiv:2408.01158, 2024 - arxiv.org
We derive the effective medium theory for the linearized time-domain acoustic waves
propagating in a bubbly media. The analysis is done in the time-domain avoiding the need …

Acoustic Cavitation using Resonating MicroBubbles: Analysis in the Time-Domain

A Mukherjee, M Sini - SIAM Journal on Mathematical Analysis, 2023 - SIAM
We study the time-domain acoustic wave propagation in the presence of a microbubble. This
microbubble is characterized by a mass density and bulk modulus which are both very small …

Effective Medium Theory for Heat Generation Using Plasmonics: A Parabolic Transmission Problem Driven by the Maxwell System

X Cao, A Mukherjee, M Sini - arxiv preprint arxiv:2411.18091, 2024 - arxiv.org
Exciting nanoparticles with incident frequencies close to their (subwavelength) resonances
generate heat in the surrounding medium. Estimating the amount of heat generated is …

Time-dependent acoustic waves generated by multiple resonant bubbles: application to acoustic cavitation

A Mukherjee, M Sini - Journal of Evolution Equations, 2024 - Springer
We analyse the ultrasound waves reflected by multiple bubbles in the linearized time-
dependent acoustic model. The generated time-dependent wave field is estimated close to …

A New Class of Uniformly Stable Time-Domain Foldy–Lax Models for Scattering by Small Particles. Acoustic Sound-Soft Scattering by Circles

M Kachanovska - Multiscale Modeling & Simulation, 2024 - SIAM
In this work we study time-domain sound-soft scattering by small circles. Our goal is to derive
an asymptotic model for this problem that is valid when the size of the particles tends to zero …

Inverse obstacle scattering for elastic waves in the time domain

L Zhao, H Dong, F Ma - Inverse Problems, 2022 - iopscience.iop.org
This paper concerns an inverse elastic scattering problem which is to determine a rigid
obstacle from time domain scattered field data for a single incident plane wave. By using the …

Wave propagation in pure-time modulated step media with applications to temporal-aiming

M Sini, H Wang, Q Yao - arxiv preprint arxiv:2312.09587, 2023 - arxiv.org
We analyze the propagation of an incident electromagnetic wave in a purely-time modulated
medium. Precisely, we assume that the permeability is unchanged while the permittivity has …
