Formation of the Reflected and Refracted s-Polarized Electromagnetic Waves in the Fresnel Problem from the Viewpoint of Molecular Optics

Abstract

Point dipoles are scattering elements of a medium. The medium consists of plane-parallel dipole monolayers influencing one another. Dipole fields are completely taken into account. The fields inside the medium and the reflected fields are calculated. The extinction theorem is analyzed in detail. The mechanism of rotation of the magnetic field vector during refraction is elucidated. A reason for the absence of the fourth wave propagating from the medium toward the boundary in the conventionally employed boundary conditions is elucidated. It is demonstrated that the interdipole interaction within a single monolayer leads to the occurrence of spatial harmonics in forward propagating radiation.
