Scattering at Interluminal Interfaces
Zhiyu Li, Klaas De Kinder, Xikui Ma +1
Scattering at interluminal modulation interfaces, where a sharp space-time perturbation moves at a velocity lying between the wave velocities of the two surrounding media, has rema…

Dispersion-Mediated Space-Time States
Klaas De Kinder, Christophe Caloz
Space-time varying media enable unprecedented control over electromagnetic waves, yet most existing studies assume idealized, nondispersive materials and thus fail to capture the i…

Scattering and Chirping at Accelerated Interfaces
Klaas De Kinder, Amir Bahrami, Christophe Caloz
Space-time varying media with moving interfaces unlock new ways to manipulate electromagnetic waves. Yet, analytical solutions have been mostly limited to interfaces moving at cons…
