In a simple realization, we consider a massless bulk field that interacts only with fields localized on the brane. We assume an initial field configuration that has the form of a wave-packet moving towards the brane. During the reflection of the wave-packet by the brane the localized fields can be excited through parametric resonance. The mechanism is also applicable to bulk fields with a potential. The rapid energy transfer can have important cosmological and astrophysical implications. (C) 2004 Elsevier B.V. All rights reserved." }
