percolation

https://doi.org/10.1351/goldbook.08847
Formation of the long-range (infinite) functional connectivity in a disperse system composed of small active particles evenly dispersed in an inactive matrix, which makes the system penetrable for a fluid or current.
Notes:
  1. The term percolation is derived from latin word percōlāre that means to filter. Porous materials in which percolation of pores exists can act as filters (pores are “active particles”). In hydrology and geology percolation relates to a slow penetration of water (liquids) through a porous material.
  2. Percolation is achieved at so-called percolation threshold and exists above it.
