Exceptional Points, Lasing, and Coherent Perfect Absorption in Floquet Scattering Systems
David Globosits, Puneet Garg, Jakob Hüpfl +4
Periodically time-varying media, known as photonic time crystals (PTCs), provide a promising platform for observing unconventional wave phenomena. We analyze the scattering of elec…

Pseudounitary Floquet scattering matrix for wave-front shaping in time-periodic photonic media
David Globosits, Jakob Hüpfl, Stefan Rotter
The physics of waves in time-varying media provides numerous opportunities for wave control that are unattainable with static media. In particular, Floquet systems with a periodic…
