Light pulse propagation through a dielectric slab. II. Two roads to the same field: numerical cross-validation of local (FDTD-ADE) and non-local (retarded integral-equation) solutions
Giancarlo Reali
Paper I of this series (arXiv:2610.29336) solves, via the retarded Green's functions, the local differential equations governing light propagation in a plane-parallel dielectric sl…

Light pulse propagation through a dielectric slab. I. Retarded integral equations and their local finite-difference solution
Giancarlo Reali
We describe the propagation of a nonresonant light pulse normally incident on a thin dielectric slab using an integral-equation approach to electromagnetism. This emerges naturally…

Light propagation in dielectric materials
Ledo Stefanini, Giancarlo Reali
We present a pedagogic derivation of the electromagnetic field established in a dielectric material by an impinging external field. We consider the problem from the point of view o…
