Scattering of electromagnetic waves by charged particles
Abstract
The behavior of charged dielectric spherical (aerosol) particles in an external electromagnetic field is analyzed. The position of the dipole plasma resonance on the particle is determined, assuming that electrons, interacting via Coulomb potential, move freely on the particle surface. The vertex equation is solved in the chaotic phase approximation. A calculation is made of surface plasmon damping due to the thermal decay of plasma oscillations into single particle excitations. Since the plasmon damping is small, the elastic scattering cross section can increase by many order of magnitude near resonance. The possibility of the experimental detection of this resonance is discussed.
