Study of energy backflow in unidirectional monochromatic and space-time waves

P Saari, I Besieris - arxiv preprint arxiv:2405.02284, 2024 - arxiv.org
Backflow, or retropropagation, is a counterintuitive phenomenon whereby for a forward-
propagating wave the energy locally propagates backward. In this study, energy backflow …

Spatiotemporal steering of non-diffracting wavepackets

H Wang, C Guo, S Fan - arxiv preprint arxiv:2501.10577, 2025 - arxiv.org
We study the dynamics of space-time non-diffracting wavepackets, commonly known as light
bullets, in a spatiotemporally varying medium. We show that by spatiotemporal refraction, a …
