Abstract
We measured the complex dielectric constant of a percolative metal-insulator system below pc, in two and three dimensions. In 2D, a perfect agreement with the scaling theory is observed, but in 3D the agreement is good only at low frequency.
Résumé
On a mesuré la constante diélectrique complexe d'un système métal-isolant percolant, au-dessous de pc, à deux et trois dimensions. A 2D on observe un accord parfait avec la théorie des lois d'échelle, mais à 3D, l'accord n'est bon qu'a basse fréquence.
