Abstract
The problem of scattering and absorption of electromagnetic radiation by particles can be solved analytically for only the simplest case, but established numerical methods allow a straightforward extension to particles with arbitrary homogeneities, arbitrary shapes, and nonlinear response. In this paper a recently developed frequency domain method involving CFD techniques is reviewed and applied to the problem of a dielectric coated sphere of arbitrary size parameter. Numerical results are in good agreement with analytical solutions. The problem is solved via the Debye amplitude formulation and then the field observables such as the heat generation are calculated. Results obtained suggest that finite element methods have promise for analytically intractable scattering/absorption problems.
