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…
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…
Space-Time Graded-Index Interfaces and Related Chirping
Zhiyu Li, Xikui Ma, Klaas De Kinder +2
Space-time modulated systems have recently emerged as a powerful platform for dynamic electromagnetic processing in both space and time. Most of the related research so far has ass…
Analog OFDM based on Real-Time Fourier Transformation
Xiaolu Yang, Oscar Céspedes Vicente, Christophe Caloz
This paper proposes an analog orthogonal frequency division multiplexing (OFDM) architecture based on the real-time Fourier transform (RTFT). The core enabling component is a linea…
Doppler Pulse Amplification
Klaas De Kinder, Amir Bahrami, Christophe Caloz
The ability to amplify ultrashort pulses has revolutionized modern laser science, driving advances in various fields such as ultrafast optics and spectroscopy. A pivotal developmen…
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…
