Singular integral equations method for computations of the scattering characteristics of a model heart exposed to electromagnetic radiation

摘要

The singular integral equations method elaborated in this paper allows us to solve accurately the Maxwell’s equations for a three-dimensional (3D) model heart exposed to electromagnetic radiation in the frequency range SHF and EHF. To test our algorithm we have computed the back scattering cross-section for a metal disc. Our computations are in good agreement with experiment given in literature. To demonstrate the usefulness of the algorithm we have computed the scattering characteristics of a simplified model of the human heart. This model is composed of the myocardium, the right and left atria and ventricles. All surfaces of the model are defined a triangular mesh in 3D covering the heart surfaces and normals n→ to the triangles.
