Özet:

 

Influence of the number of particles considered in numerical  simulations on the complex dielectric permittivity of binary dilute  dielectric mixtures in two-dimensions are reported.  In the  simulations, dodecagons (polygons with 12-sides) were used to mimic  disk-shaped inclusions.  Using such an approach we were able to  consider 162 particles in a unit-square.  The effective dielectric  permittivity of the mixtures were calculated using the finite element  method at two different frequecies which were much higher and lower  than the characteristic relaxation rate of the Maxwell-Wagner-Sillars  polarization.  The results were compared to an analytical solution.   It was found that the permittivity values at low frequencies were  inside Wiener bounds; however they violated the Hashin-Shtrikman  bounds.
