Space-Time Event Scattering and Extension Method (STESEM): A Universal Framework for Scattering in Space-Time Metamaterials
Klaas De Kinder, Amir Bahrami, Christophe Caloz
Space-time metamaterials offer unprecedented control over electromagnetic waves by enabling simultaneous manipulation of spatial and temporal degrees of freedom. However, analytica…
Space-Time Lensing by Accelerated Interfaces in Dispersive Media
Cédric D'Exelle, Klaas De Kinder, Christophe Caloz
The paper proposes a method to focus or collimate optical pulses using synthetic accelerated interfaces in dispersive media, designing the interface trajectory to control space‑tim…
Scattering at Space-Time Interfaces between Dispersive Media
Klaas De Kinder, Christophe Caloz
Dynamic modulation of material properties in space and time enables powerful control over wave propagation, yet existing theories largely rely on idealized, nondispersive models. I…
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…
