Accurate determination of the dielectric parameters of spherical shells in suspension

Abstract

A novel, self-consistent, algebraic method is developed within the framework of Maxwell-Wagner theory (i.e., 'mixture formula' and single shell model) for obtaining the dielectric parameters, such as ε_s, κ_s and f_Q of spherical shells. The efficacy of the procedure that—in contrast to previous ones—is void of any approximations, was successfully tested by reanalyzing existing data on polystyrene microcapsules.
