PREDICTION OF THE PERMITTIVITY OF RANDOM COMPOSITES BY MORPHOLOGICAL MODELING

Morphological models of textures are available to simulate the geometr y of two phase composites and to predict their macroscopic physical be haviour: for random mosaics built on a random tessellation, Boolean mo dels, Dead Leaves models, or combinations of these models, third order correlation functions, can be calculated theoretically; this is used to predict their macroscopic complex dielectric permittivity, using th e derivations of D.J. Bergman and G. Milton, and to look for optimal t extures with respect to the material behaviour.
