Mathematical foundations of the non-Hermitian skin effect
Habib Ammari, Silvio Barandun, Jinghao Cao +2
We study the skin effect in a one-dimensional system of finitely many subwavelength resonators with a non-Hermitian imaginary gauge potential. Using Toeplitz matrix theory, we prov…
Design of defected non-hermitian chains of resonator dimers for spatial and spatio-temporal localizations
Habib Ammari, Erik Orvehed Hiltunen, Thea Kosche
The aim of this article is to advance the field of metamaterials by proposing formulas for the design of high-contrast metamaterials with prescribed subwavelength defect mode eigen…
Transmission properties of time-dependent one-dimensional metamaterials
Habib Ammari, Jinghao Cao, Erik Orvehed Hiltunen +1
We solve the wave equation with periodically time-modulated material parameters in a one-dimensional high-contrast resonator structure in the subwavelength regime exactly, for whic…
Edge modes in subwavelength resonators in one dimension
Habib Ammari, Silvio Barandun, Jinghao Cao +1
We present the mathematical theory of one-dimensional infinitely periodic chains of subwavelength resonators. We analyse both Hermitian and non-Hermitian systems. Subwavelength res…
