DISORDER EFFECTS ON THE EFFECTIVE DIELECTRIC RESPONSE OF A LINEAR-CHAIN OF POLARIZABLE SPHERES

We perform a numerical simulation in order to calculate the dielectric response, to a long wavelength external field, for a linear chain of polarizable spheres embedded in a homogeneous host. The dielectric res ponse is calculated within the dipolar, quasi-static approximation, an d the position of each sphere is generated using three different types of disorder algorithms. The induced dipole moment on each sphere is c alculated by solving a set of linear equations and using periodic boun dary conditions. The imaginary part of the dielectric response as a fu nction of frequency is shown and analyzed for the three types of disor der. These are also characterized through the calculation of the two-p article distribution function of the spheres.
