Reconstructing fine details of small objects by using plasmonic spectroscopic data. Part II: The strong interaction regime
Habib Ammari, Matias Ruiz, Sanghyeon Yu +1
This paper is concerned with the inverse problem of reconstructing a small object from far field measurements by using the field interaction with a plasmonic particle which can be…
Field expansions for systems of strongly coupled plasmonic nanoparticles
Habib Ammari, Matias Ruiz, Sanghyeon Yu +1
This paper is concerned with efficient representations and approximations of the solution to the scattering problem by a system of strongly coupled plasmonic particles. Three schem…
Double-negative acoustic metamaterials
Habib Ammari, Brian Fitzpatrick, Hyundae Lee +2
The aim of this paper is to provide a mathematical theory for understanding the mechanism behind the double-negative refractive index phenomenon in bubbly fluids. The design of dou…
Bloch waves in bubbly crystal near the first band gap: a high-frequency homogenization approach
Habib Ammari, Hyundae Lee, Hai Zhang
This paper is concerned with the high-frequency homogenization of bubbly phononic crystals. It is a follow-up of the works [H. Ammari et al., Sub-wavelength phononic bandgap openin…
Sub-wavelength focusing of acoustic waves in bubbly media
Habib Ammari, Brian Fitzpatrick, David Gontier +2
The purpose of this paper is to investigate acoustic wave scattering by a large number of bubbles in a liquid at frequencies near the Minnaert resonance frequency. This bubbly medi…
Scattering by a periodic array of subwavelength slits II: surface bound state, total transmission and field enhancement in homogenization regimes
Junshan Lin, Hai Zhang
This is the second part in a series of two papers that concern with the quantitative analysis of the electromagnetic field enhancement and anomalous diffraction by a periodic array…
Scattering by a periodic array of subwavelength slits I: field enhancement in the diffraction regime
Junshan Lin, Hai Zhang

Reconstructing fine details of small objects by using plasmonic spectroscopic data
Habib Ammari, Matias Ruiz, Sanghyeon Yu +1
This paper is concerned with the inverse problem of reconstructing a small object from far field measurements. The inverse problem is severally ill-posed because of the diffraction…
Characterization of the essential spectrum of the Neumann-Poincaré operator in 2D domains with corner via Weyl sequences
Eric Bonnetier, Hai Zhang
The Neumann-Poincaré (NP) operator naturally appears in the context of metamaterials as it may be used to represent the solutions of elliptic transmission problems via potentiel th…
Subwavelength phononic bandgap opening in bubbly media
Habib Ammari, Brian Fitzpatrick, Hyundae Lee +2
The aim of this paper is to show both analytically and numerically the existence of a subwavelength phononic bandgap in bubble phononic crystals. The key is an original formula for…
