The present model delivers a useful framework for the transition between the analytical high frequency regime and the extreme low frequency limit described by models based on Fukuyama's {\it et al.} (Phys. Rev. B {\bf 8}, 5579 (1973)) proposal.5 pages, 6 figures ps, RevtexMesoscale and Nanoscale Physicstext
