The theory of second harmonic generation (SHG) in three-dimensional structures consisting of arbitrary distributions of metallic spheres made of centrosymmetric materials is developed by means of multiple scattering of electromagnetic multipole fields [27].
The nonuniform electric field applied to the PEC or PMC will induce predominantly quadrupole and higher-order multipole fields a fraction of a wavelength outside the circumscribing sphere, and reactive fields between [S.sub.a] and a fraction of a wavelength outside the circumscribing sphere, but with a ratio of the energy stored in the reactive fields to the power radiated by the electric dipole that increases faster with decreasing electrical size of [V.sub.a] than the same ratio for the fields induced by the uniform electric field [4].
This field is a function of both the applied and multipole fields in the media.
Laplace's equations in dimensions higher than 3 correspond to electric multipole fields of order 1, where 1 = n - 3.
If ka is below this value it cost much power to add currents that radiate multipole fields of index l, or higher.
For the proposed setup, the volume between two nested cylinders made from magnetic multipole fields is used to store the UCN (Fig.
studied the scattering of a Hermite-Gaussian beam by a chiral sphere by using the relations between the multipole fields and the conventional Hermite-Gaussian beam [23].
