Abstract: The a.c. electric field distribution is studied in composite, containing materials with small local losses. The possibility that a 2D two-component system can have effective absorption in the absence of local absorption was evidenced (A.M. Dykhne, Zh. Eksp. Teor. Fiz. 59 (1970) 110). We study the second and higher moments of electric field and show taht they diverge with the decrease of local absorption. The 3D system near the percolation threshold is also discussed. The observation of giant field fluctuations in granular films first discovered by Brouers et al. and Lagarkov et al. is explained.
