Abstract
The time-dependent density-functional approach is used to calculate the dynamic image-plane position of a metal surface for external fields that vary exponentially in time and slowly in space. This image plane determines the reference plane of the atom-metal van der Waals interaction which is evaluated for He and interacting with several simple- and noble-metal surfaces.
