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…

Newton's second law: not so elementary (as it may seem)
Ledo Stefanini, Giancarlo Reali
We propose an interpretation of the Newton's second law that is suggested by Galilean Relativity theory.

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…
