In the late 1960s and early 1970s, Dubovik [24,25] connected the quantum description of the anapole to classical electrodynamics by introducing the polar toroidal multipole moments. The term toroidal derives from current distributions in the shape of a circular coil that were first shown to have a toroidal moment.
The first term in (23) can be considered as the quantized rotation energy of the drop; the second one is the quantized electrostatic energy due to the multipole moments of the charged drop.
with [Q.sub.l] as an l multipole moment of the drop.
We investigate the test particle motion in axially symmetric gravitational potentials that are the sum of monopolar, quadrupolar and octupolar terms (only external multipole moments will be considered).
Instead of being evaluated directly, the local moments are derived by a linear mapping acting on the multipole moments in the FM framework.

We introduce in this paper new multipole moments and transfer functions for O(N log N) scheme and new formulas for the translations from multipole to multipole, multipole to local, and local to local that are necessary to construct the O(N) scheme for solving the 3D particulate Stokes problem.
Nevertheless, according to the general theory of the light interaction with nano-sized spheres (Mie theory) [23, 24], the spectrum of each separate nano-particle depends on parameter kua (k is the wave number in a medium surrounding nano-object) which determines the predominate role of multipole moments of one or another order in the scattering field decomposition.
In the approach of Mazur, Robinson, and Jackson (27), (29), (30) the charge density is expanded in a Taylor series and the multipole moments are identified as in Eq.
Solutions of the Laplace equation in cylindrical coordinates are considered, these represent the gravitational field of objects with only external multipole moments. The physical quantities in the plane of the disk, are defined and calculated such as, the epicyclic frequency, k, the vertical frequency, v, and the circular velocity, [v.sub.c] of particles.
In this paper, we present a low-frequency scattering analysis for discovering the quasi-static multipole moments of a split-ring element for different types of incidence and an application of the derived dipole moments to medium homogenisation.
