Analysis of Laser-Driven Particle Acceleration fromPlanar Transparent Boundaries

This article explores the interaction between a monochromatic plane wave laser beam and a relativistic electron in the presence of a thin dielectric transparent boundary. It is found that the sign of the interaction between the laser and the electron in the downstream space is determined by the optical phase delay of the laser caused by the boundary, and that it can add to or cancel the interaction in the upstream space. Both the inverse-transition radiation picture and the electric field path integral method show this result.
