Propagation of light from dipole source and generalization of Fresnel-Kirchhoff integral

摘要

The elementary system which can emit light is a dipole. Theoretical method of light propagation from point like dipole source is presented in this paper. The propagation is considered through two media divided by 3D arbitrary surface. Orientation of new formed dipole on surface segment is determined according to the refraction of incident wave-front electric field strength on boundary surface. Generalized formulation of Fresnel-Kirchhoff integral is derived for elementary dipole as a source and arbitrary surface dividing two media with arbitrary refraction indexes.
