CONTINUUM PERCOLATION CONDUCTIVITY EXPONENTS IN RESTRICTED DOMAINS

Conductivity behavior of continuum percolation in restricted two-dimen sional domains is simulated by considering systems of randomly distrib uted disks. The domain is restricted in that conducting objects are pe rmitted to lie in only a portion of the domain. Such a restricted doma in might better approximate some natural systems. Simulations of two-d imensional systems, based on three distributions of local conductances , are examined and found to demonstrate a power-law behavior with cond uctivity exponents smaller than those arising in regular lattice and c ontinuum percolation.
