Rezumat:

In this work, we consider low contrast periodic media and we study the dependence
of the effective or homogenized tensor and the dispersion tensor in terms of the
microstructure. We treat both one-dimensional structures and some laminated structures
in higher dimension. Interesting properties of the sign of these coefficients are
found. Surprisingly, these depend on the microstructure only through the local
proportion parameter, and in some cases, they do not depend on the microstructure
at all.
