Super-resolution in high contrast media
Habib Ammari, Hai Zhang
A mathematical theory is developed to explain the super-resolution and super-focusing in high contrast media. The approach is based on the resonance expansion of the Green function…
Surface Plasmon Resonance of Nanoparticles and Applications in Imaging
Habib Ammari, Youjun Deng, Pierre Millien
In this paper we provide a mathematical framework for localized plasmon resonance of nanoparticles. Using layer potential techniques associated with the full Maxwell equations, we…
Multi-frequency acousto-electromagnetic tomography
Giovanni S. Alberti, Habib Ammari, Kaixi Ruan
This paper focuses on the acousto-electromagnetic tomography, a recently introduced hybrid imaging technique. In a previous work, the reconstruction of the electric permittivity of…
Super-resolution in Imaging High Contrast Targets from the Perspective of Scattering Coefficients
Habib Ammari, Yat Tin Chow, Jun Zou
In this paper we consider the inverse scattering problem for high-contrast targets. We mathematically analyze the experimentally-observed phenomenon of super-resolution in imaging…
Magnetic resonance-based reconstruction method of conductivity and permittivity distributions at the Larmor frequency
Habib Ammari, Hyeuknam Kwon, Yoonseop Lee +2
Magnetic resonance electrical property tomography is a recent medical imaging modality for visualizing the electrical tissue properties of the human body using radio-frequency magn…
Stability Analysis for Magnetic Resonance Elastography
Habib Ammari, Alden Waters, Hai Zhang
We consider the inverse problem of finding unknown elastic parameters from internal measurements of displacement fields for tissues. The measurements are made on the entirety of a…
