Abstract
The backbone fractal dimension dBf is calculated on two-dimensional percolation clusters at the percolation threshold. Studies are carried out on backbones defined in three different ways: bus bar, point-to-point, and with fully periodic boundaries. The estimates of dBf are obtained by measuring the variation of mass with radius for all clusters, and by means of finite size scaling on the bus bar backbones. All cases imply a value of dBf=1.64+or-0.01 for the backbone fractal dimension. Because of the high degree of self-consistency of all the results, the authors believe that this estimate represents a considerably improved accuracy.Keywords
