Abstract
A dielectric theory of interfacial polarization is presented for a heterogeneous system containing ellipsoidal particles covered with shells, in order to make an analysis of dielectric behavior of suspensions of ellipsoidal biological cells. For the case of spheroidal shapes, dielectric dispersion curves are calculated numerically by using the electrical and morphological parameters relevant to biological cells. The results indicate that the calculated dielectric dispersion curves are seriously affected by varying the axial ratio of the spheroids. For the purpose of analyzing dielectric data of biological cell suspensions on the basis of the presented theory, a procedure is proposed to evaluate electrical parameters characteristic of biological cells. This procedure is shown to be successfully applied to the observed dielectric data of erythrocyte suspensions.
