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…
Symmetry-induced quasicrystalline waveguides
Bryn Davies, Richard V Craster
Introducing an axis of reflectional symmetry in a quasicrystal leads to the creation of localised edge modes that can be used to build waveguides. We develop theory that characteri…
Bioinspired random projections for robust, sparse classification
Nina Dekoninck Bruhin, Bryn Davies
Inspired by the use of random projections in biological sensing systems, we present a new algorithm for processing data in classification problems. This is based on observations of…
Anderson localization in the subwavelength regime
Habib Ammari, Bryn Davies, Erik Orvehed Hiltunen
In this paper, we use recent breakthroughs in the study of coupled subwavelength resonator systems to reveal new insight into the mechanisms responsible for the fundamental feature…
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…
Asymptotic characterisation of localised defect modes: Su-Schrieffer-Heeger and related models
Richard V Craster, Bryn Davies
Motivated by topologically protected states in wave physics, we study localised eigenmodes in one-dimensional periodic media with defects. The Su-Schrieffer-Heeger model (the canon…
