Descrição: 27The problem of the diffraction of electromagnetic waves by a dielectric body with perturbed boundary has been considered using the boundary perturbation technique. The solution is valid for the near zone (i. e., near the dielectric body) as well as for the far zone and is good for all frequencies. Since the perturbation solution satisfies Maxwell's equations, the boundary conditions, and the radiation condition for the scattered wave at infinity, hence it is unique. It should be noted that with slight modifications the derived results are also applicable for a radially inhomogeneous dielectric body with perturbed boundary. Further applications of this perturbation technique can be found in the scattering of electromagnetic or acoustic waves from hard or soft objects, in the scattering of x-ray or of light by interstellar matter, and in elementary particle scattering, theory.
