Time Refraction and Time Reflection above Critical Angle for Total Internal Reflection

L Bar-Hillel, A Dikopoltsev, A Kam, Y Sharabi… - Physical Review Letters, 2024 - APS
We study the time reflection and time refraction of waves caused by a spatial interface with a
medium undergoing a sudden temporal change in permittivity. We show that monochromatic …

Temporal transfer matrix method for Lorentzian dispersive time-varying media

F Feng, N Wang, GP Wang - Applied Physics Letters, 2024 - pubs.aip.org
Incorporating dispersion into time-varying media not only holds practical significance but
also profoundly transforms the electromagnetic characteristics of such dynamic media. In …

Time-Domain Bound States in the Continuum

O Schiller, Y Plotnik, O Segal, M Lyubarov… - arXiv preprint arXiv …, 2024 - arxiv.org
We present the concept of time-domain bound states in continuum. We show that a rapid
judiciously-designed temporal modulation of the refractive index in a spatially homogenous …
