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…
MIMO Capacity Enhancement by Grating Walls: A Physics-Based Proof of Principle
Xiaolu Yang, Oscar Cespedes Vicente, Christophe Caloz
The paper demonstrates how coating indoor walls with binary gratings can passively boost MIMO spectral efficiency by enriching non‑line‑of‑sight multipath and reducing channel corr…
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…
Access to Klein Tunneling via Space-Time Modulation
Furkan Ok, Amir Bahrami, Christophe Caloz
We show that space-time modulation of electromagnetic potentials enables Klein tunneling far below the static threshold. The derived kinematics reveal oblique transitions that can…
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…
