A mathematical design strategy for highly dispersive resonator systems
Konstantinos Alexopoulos, Bryn Davies
Designing devices composed of many small resonators is a challenging problem that can easily incur significant computational cost. Can asymptotic techniques be used to overcome thi…
Asymptotic analysis of subwavelength halide perovskite resonators
Konstantinos Alexopoulos, Bryn Davies
Halide perovskites are promising materials with many significant applications in photovoltaics and optoelectronics. In this paper, we use integral methods to quantify the resonant…
Robustness of subwavelength devices: a case study of cochlea-inspired rainbow sensors
Bryn Davies, Laura Herren
The aim of this work is to derive precise formulas which describe how the properties of subwavelength devices are changed by the introduction of errors and imperfections. As a demo…
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…
