title: Time delay associated with total reflection of a plane wave upon plasma mirror.
abstract: By employing both the ray model and the electromagnetic theory in a slab optical waveguide, we show that the Goos-Hänchen time, which has been recently argued in the literature, really exists and the time associated with total reflection of a plane wave upon nonabsorbing plasma mirror is exactly the sum of the group delay time and the Goos-Hänchen time. Based on this concept, it is also indicated that the causality is preserved not only for the frustrated Gires-Tournois interferometer case but also for the case of total reflection of a plane TM wave on a nonabsorbing plasma mirror.
