Abstract

We study the continuum percolation in systems composed of overlapping objects of two different sizes. We show that when treated as a function of the volumetric fraction f as opposed to the concentration x, the percolation threshold exhibits the symmetry ηc(f,r)=ηc(1−f,r) where r is the ratio of the volumes of the objects. Knowledge of this symmetry has the following benefits: (i) the position of the maximum of the percolation threshold is then known to be at exactly f=1/2 for any r and (ii) full knowledge of the percolation threshold is obtained by performing simulations only for f∈[0,12] or f∈[12,1], whichever is computationally easier.
