Time-dependent high-contrast subwavelength resonators
Habib Ammari, Erik Orvehed Hiltunen
In the field of metamaterials, many intriguing phenomena arise from having a structure which is periodic in space. In time-dependent structures, conceptually similar properties can…
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…
Edge modes in active systems of subwavelength resonators
Habib Ammari, Erik Orvehed Hiltunen
Wave scattering structures with amplification and dissipation can be modelled by non-Hermitian systems, opening new ways to control waves at small length scales. In this work, we s…
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…
