Decay of molecules at corrugated thin metal films

: The problem of the decay rate for molecules at corrugated thin metal films is considered theoretically via a classical phenomenological approach by generalizing a previous theory for a single rough surface. In particular, numerical results are worked out in detail for grating films with various possible arrangements of the two grating surfaces, and for both the cases with a supported and free-standing film. Effects due to cross-coupling into the long- and short-range surface plasmons are observed, and correlations to recent experiments performed by the Rochester group are made.
