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…

Non-reciprocal wave propagation in space-time modulated media
Habib Ammari, Jinghao Cao, Erik Orvehed Hiltunen
We prove the possibility of achieving non-reciprocal wave propagation in space-time modulated media and give an asymptotic analysis of the non-reciprocity property in terms of the…
