Abstract
It is shown that large percolation-enhanced nonlinear scattering occurs in metal-dielectric random composites near the percolation threshold. The enha ncement is due to giant local electric field fluctuations that are extremel y inhomogeneous and consist of spatially separated sharp peaks, ''hot'' spo ts, where the local field is greater by many orders of magnitude than the a pplied field.
