Dynamics of Dipoles and Their Interaction with Radio Waves

Abstract

We calculate the shapes, dimensions, density distributions, and orientations of dipoles in clouds consisting of millions of the dipoles, which are formed during fractions of a second when such clouds are injected into air at a high speed, using the three-dimensional nonstationary formulation and applying the Monte Carlo method and aerodynamics equations for the motion of electric dipoles. The values of the optical density, radiation intensity, and backscattering cross sections of such clouds are calculated for different directions and polarizations of the incident and detected scattered resonance and nonresonance radiation. Great influence of small distortions in the rectilinear form of the dipoles is demonstrated. It is shown that a great part of the dipoles of metallized fiberglass does not take part in the scattering due to shielding, which reduces the backscattering cross sections by many times.
