Y. Yagil, SCALING THEORY FOR THE OPTICAL-PROPERTIES OF THICK PERCOLATIVE METAL-INSULATOR FILMS, Journal of physics. Condensed matter, 6(48), 1994, pp. 10607-10615
The 2D scaling approach for the optical properties of semicontinuous m
etal films is generalized to thick (3D) percolative films. Model calcu
lations demonstrate that the scaling model is qualitatively different
from any effective medium approach, and should be used whenever the in
homogeneity length scale is larger than the optical one.
