EFFECTIVE PROPERTIES FOR SYSTEMS WITH DISTRIBUTED RESISTANCES IN CONTINUOUS SPACE

A system with exponentially distributed resistances is examined here. The importance of field and current distribution inside each resistanc e is shown to be a necessary sign of the so-called continual problem. Consideration of this current distribution leads to a further increase of the relative spectral density of 1/f noise and the appearance of a nother critical exponent in comparison with a discrete problem. The cr itical exponent connected with the inhomogeneity of current distributi on inside each resistance has been evaluated. [S0163-1829(97)07041-0].
