Bound states in the continuum and Fano resonances in subwavelength resonator arrays
Habib Ammari, Bryn Davies, Erik Orvehed Hiltunen +2
When wave scattering systems are subject to certain symmetries, resonant states may decouple from the far-field continuum; they remain localized to the structure and cannot be exci…
Wave interaction with subwavelength resonators
Habib Ammari, Bryn Davies, Erik Orvehed Hiltunen +2
The aim of this review is to cover recent developments in the mathematical analysis of subwavelength resonators. The use of sophisticated mathematics in the field of metamaterials…
High-order exceptional points and enhanced sensing in subwavelength resonator arrays
Habib Ammari, Bryn Davies, Erik Orvehed Hiltunen +2
Systems exhibiting degeneracies known as exceptional points have remarkable properties with powerful applications, particularly in sensor design. These degeneracies are formed when…
Exceptional points in parity-time-symmetric subwavelength metamaterials
Habib Ammari, Bryn Davies, Erik Orvehed Hiltunen +2
When sources of energy gain and loss are introduced to a wave-scattering system, the underlying mathematical formulation will be non-Hermitian. This paves the way for the existence…
Quantitative estimates for stress concentration of the Stokes flow between adjacent circular cylinders
Habib Ammari, Hyeonbae Kang, Do Wan Kim +1
When two inclusions with high contrast material properties are located close to each other in a homogeneous medium, stress may become arbitrarily large in the narrow region between…
Close-to-touching acoustic subwavelength resonators: eigenfrequency separation and gradient blow-up
Habib Ammari, Bryn Davies, Sanghyeon Yu
In this paper, we study the behaviour of the coupled subwavelength resonant modes when two high-contrast acoustic resonators are brought close together. We consider the case of sph…
