Percolation theory was recognized from its inception as a conceptual
model with application to fluid movement in porous media. But while it
clearly has much to contribute to our understanding of porous media, it
is currently more a curiosity than a tool in the hydrogeological and
geophysical mainstream. This mini-symposium will bring together
researchers in porous media and percolation theory to examine the
connections between the two. What are the applications of percolation
theory to porous media? What are the inherent limitations of applying
the mathematical theory to physical objects, and what adaptations must
be made? Are there related models and/or concepts that can be wedded to
percolation theory to broaden its applicability? What critical issues
in porous media are currently begging for a solution that percolation
theory could provide?

This minisymposium, will be held Monday afternoon of the conference will include the following talks (please click on the titles to see the abstracts):

Correlation structure effects on edge-accessible porosity and chemical distance near the percolation threshold

The topics to be covered in this minisymposium are planned to give a sample of
some of the existing mathematical tools available to model heterogeneous
electromagnetic and magnetic problems such as, but not limited to, the
following: homogenization of linear and non-linear Maxwell's equations;
bounds on the effective properties; and localization effects in periodic and
non-periodic structures.

Two topics will be covered in this minisymposium. One is 'random lasers' in
which there will be four talks; two talks on experimental works and the other
two talks on theoretical issues. The novel and fascinating properties of
random lasers are still a mystery, and these talks will give a sample of the
many facets associated with this type of laser action.
The other topic is 'conducting polymers' in which there will be also four
talks, all on experimental works. One talk describes the electrical properties
of doped polymers, the other three talks deal with optical properties of
several conducting polymer films, including femtosecond transient, cw
photomodulation, and spin dependent photomodulation. These talks will give a
sample on the many properties of conducting polymers, the novel materials that
were the subject of the 2000 Nobel Prize in Chemistry.
