Abstract

Finite element calculations of frequency dependent dielectric permittivity of different binary system composed of conductive cylindrical inclusions in a less conductive matrix are presented. The inclusions were distributed regularly in three different geometrical structures. The smallest repeatable units of the structures were used in the computations. The relative permittivities of the inclusions and matrix were taken to be the same and equal to 4, whereas their conductivities were 1 X 10^-7 and 1 X 10^-20 ((Omega) X m)^-1, respectively. The systems showed classical Debye behavior. An increase in the dielectric constant at the low frequency side as observed with did not show any differences when q <EQ 0.30. However, the relative permittivities were not the same for different lattices at higher q values. This effect was due to the interaction of the inclusions with each other.
