Effects of poly-dispersity on continuum percolation

Autor: Keiji Okazaki, Ryusei Ogata, Takashi Odagaki

Publikováno v: Journal of Physics: Condensed Matter. 17:4531-4538

The continuum percolation process of particles with a size distribution is investigated by Monte Carlo simulation. The critical area (volume) fraction of particles at the percolation threshold in two (three) dimensions is determined for various distr
