Dielectric scaling near a percolation threshold

Ludovic Benguigui

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.
