A high-frequency homogenization approach near the Dirac points in bubbly honeycomb crystals
Habib Ammari, Erik Orvehed Hiltunen, Sanghyeon Yu
In [H. Ammari et al., Honeycomb-lattice Minnaert bubbles. arXiv:1811.03905], the existence of a Dirac dispersion cone in a bubbly honeycomb phononic crystal is shown. The aim of th…
Honeycomb-lattice Minnaert bubbles
Habib Ammari, Brian Fitzpatrick, Erik Orvehed Hiltunen +2
The ability to manipulate the propagation of waves on subwavelength scales is important for many different physical applications. In this paper, we consider a honeycomb lattice of…
The equivalent media generated by bubbles of high contrasts: Volumetric metamaterials and metasurfaces
Habib Ammari, Durga Prasad Challa, Anupam Pal Choudhury +1
We deal with the point-interaction approximations for the acoustic wave fields generated by a cluster of highly contrasted bubbles for a wide range of densities and bulk moduli con…
Subwavelength resonances of encapsulated bubbles
Habib Ammari, Brian Fitzpatrick, Hyundae Lee +2
The aim of this paper is to derive a formula for the subwavelength resonance frequency of an encapsulated bubble with arbitrary shape in two dimensions. Using Gohberg-Sigal theory,…
Identification of an algebraic domain in two dimensions from a finite number of its generalized polarization tensors
Habib Ammari, Mihai Putinar, Andries Steenkamp +1
This paper aims at studying how finitely many generalized polarization tensors of an algebraic domain can be used to determine its shape. Precisely, given a planar set with real al…
A direct linear inversion for discontinuous elastic parameters recovery from internal displacement information only
Habib Ammari, Elie Bretin, Pierre Millien +1
The aim of this paper is to present and analyze a new direct method for solving the linear elasticity inverse problem. Given measurements of some displacement fields inside a mediu…
