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…
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…
Space-Time Wedges
Amir Bahrami, Klaas De Kinder, Zhiyu Li +1
Space-time-modulated systems have attracted significant interest over the past decade due to their ability to manipulate electromagnetic waves in unprecedented ways. Here, we intro…
Wave-Medium Interactions in Dynamic Matter and Modulation Systems
Zhiyu Li, Xikui Ma, Zoé-Lise Deck-Léger +2
Space-time modulation systems have garnered significant attention due to their resemblance to moving-matter systems and promising applications. Unlike conventional moving-matter sy…
Space-Time Fresnel Prism
Zhiyu Li, Xikui Ma, Amir Bahrami +2
Space-time modulation-based metamaterials have recently spurred considerable interest, owing to the fundamental addition of the time dimension to the medium parameters, and resulti…
Critical Angle at a Moving Interface Formed by a Space-Time Modulation Step
Zhiyu Li, Xikui Ma, Christophe Caloz
This paper addresses the problem of wave scattering at a moving interface formed by a space-time modulation step. Specifically, it derives, using the technique of frame hopping wit…
