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…
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 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…
