Abstract
The a.c. electric field distribution is studied in a composite, containing materials with small local losses. The possibility that 2D two-component system can have effective absorption in the absence of local absorption was evidented. We study the second and higher moments of electric field and show that 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 is explained.
