An Introduction To The Mathematics Of The Imaging Modalities Using Small Scaled Contrast Agents

Ahcene Ghandriche, Mourad Sini

In the recent years, we witness a great interest in imaging, in a wide sense, using contrast agents. One of the reasons is that many imaging modalities, as the ones related to medi…

Mathematical analysis of the acoustic imaging modality using bubbles as contrast agents at nearly resonating frequencies

Alexander Dabrowski, Ahcene Ghandriche, Mourad Sini

We analyze mathematically the acoustic imaging modality using bubbles as contrast agents. These bubbles are modeled by mass densities and bulk moduli enjoying contrasting scales. T…

Mathematical Analysis of the Photo-acoustic imaging modality using resonating dielectric nanoparticles: The 2D TM-model

Ahcene Ghandriche, Mourad Sini

We deal with the photoacoustic imaging modality using dielectric nanoparticles as contrast agents. Exciting the heterogeneous tissue, localized in a bounded domain , with an ele…

Analysis of the acoustic waves reflected by a cluster of small holes in the time-domain and the equivalent mass density

Mourad Sini, Haibing Wang, Qingyun Yao

We study the time-domain acoustic scattering problem by a cluster of small holes (i.e. sound-soft obstacles). Based on the retarded boundary integral equation method, we derive the…

Direct and inverse time-harmonic elastic scattering from point-like and extended obstacles

Guanghui Hu, Andrea Mantile, Mourad Sini +1

This paper concerns the time-harmonic direct and inverse elastic scattering by an extended rigid elastic body surrounded by a finite number of point-like obstacles. We first justif…

Foldy-Lax approximation of the electromagnetic fields generated by anisotropic inhomogeneities in the mesoscale regime with complements for the perfectly conducting case

Ali Bouzekri, Mourad Sini

The Foldy-Lax (or the point-interaction) approximation of the electromagnetic fields generated by a cluster of small scaled inhomogeneities is derived in the mesoscale regime, i.e.…
