The method for calculation of the depolarizing factors of the arbitrary shape geometrical objects and biological structures
Keywords:
depolarizing factor, dielectric permittivity, dispersed particles
Abstract
The effective algorithm and program for calculation of the depolarizing factors of the arbitrary shape objects by the method of the discrete-dipole approximation have been developed. The depolarizing factors of the geometrical objects such as the plane disc, sphere, cylinder, half-sphere, cone, octahedron, helix, model of the three-dimensional structure of serum albumin and the real structure of human serum albumin which was built on the base of X-ray data (Protein Data Bank, file 1bm0) have been calculated.
