Abstract [en]

Lately there has been a regenerated interest in approximative methods for calculating low frequency electromagnetic scattering in lossy media. In this paper we focus on scattering from smooth bodies submerged in a dissipative half-space. The proposed method utilizes a surface integral formulation which is discretized using the boundary element method (BEM) and point matching. Results are given for various electromagnetic dipole sources. The incoming field is obtained from an extension of the classical ideas found in Banos [1] utilizing the Foster-Lien integral. The dyadic Green’s function needed in the surface integral equation is calculated using this quasi-static approach. The approximation is validated by a comparison with results from direct numerical integration of the Sommerfeld integrals. The speed and accuracy of the two methods is discussed.
