Abstract

The electromagnetic multiple scattering from lossless and lossy three-dimensional objects of arbitrary shape is computed using the boundary element method. Three different formulations starting from a combination of the magnetic field and the electric field integral equation are investigated. The influence of the material properties and the discretization on the solution accuracy is discussed by comparing the numerical results with analytic ones for spheres using the Mie series solution. As an example, the numerical solution of the electromagnetic scattered field of a rain drop model is presented
