Parametric amplification and bidirectional invisibility in PT-symmetric time-Floquet systems
Theodoros T. Koutserimpas, Andrea Alu, Romain Fleury
Parity-Time (PT) symmetric wave devices, which exploit balanced interactions between material gain and loss, exhibit extraordinary properties, including lasing and flux-conserving…
Zero refractive index in space-time acoustic metamaterials
Theodoros Koutserimpas, Romain Fleury
New scientific investigations of artificially structured materials and experiments have exhibit wave manipulation to the extreme. In particular, zero refractive index metamaterials…
Non-Reciprocal gain in non-Hermitian time-Floquet Systems
Theodoros T. Koutserimpas, Romain Fleury
We explore the unconventional wave scattering properties of non-Hermitian systems in which amplification or damping are induced by time-periodic modulation. These non- Hermitian ti…
