摘要
A giant increase in the static dielectric constant and a giant dielectric relaxation are predicted for a heterogeneous medium consisting of matrix-isolated spheroids and described by the Maxwell-Garnett formula. The possibility of observing collective dielectric resonance in such a medium is also discussed. (C) 2004 MAIK "Nauka / Interperiodica".
