Topological phenomena in honeycomb Floquet metamaterials
Habib Ammari, Thea Kosche
We dedicate this paper to the topological analysis of subwavelength solutions in Floquet metamaterials. This work should be considered as a basis for further investigation on wheth…

Transmission properties of space-time modulated metamaterials
Habib Ammari, Jinghao Cao, Xinmeng Zeng
We prove the possibility of achieving exponentially growing wave propagation in space-time modulated media and give an asymptotic analysis of the quasifrequencies in terms of the a…

Unidirectional edge modes in time-modulated metamaterials
Habib Ammari, Jinghao Cao
We prove the possibility of achieving unidirectional edge modes in time-modulated supercell structures. Such finite structures consist of two trimers repeated periodically. Because…
