• We ntttnerically investigate the influence of' classical percolation on the qtranttrrn Halllocalization-delocalization transition. This is acconajclished within the f'ratnework of the gera-eralized Chatlker -Coddington network naaodel which 2llI0XVS LIS to control the tattunber of classicalsaddle points l)}7 setting the width 11/ of the saddle poirat distribtrtiota. It is ['ound that increasingthis xvidth causes a new rtaicroscojoic length scale to atjvpear wlaich depends on TV and scales xviththe exponent X Z 1.36 which indicates 21 close connection to the clatssical percolation length4 and its exponent v. :: 4/3.
