Abstract [en]

Although the theory of partial polarization of uniform electromagnetic beams is well-developed, it cannot be applied to random three-dimensional (3D) waves such as optical near fields. A general formulation of partial coherence and polarization in arbitrary 3D electromagnetic fields must be based on the 3 x 3 cross-spectral density tensors. After the fundamentals of electromagnetic coherence theory, we recall some recent researches on the spatial-coherence and spectral changes brought on by surface modes and evanescent waves. Partial polarization of arbitrary electromagnetic fields containing three orthogonal components is then addressed in terms of the 3 x 3 coherence matrix, and the variation of the 3D degree of polarization in near fields generated by semi-infinite thermal sources is analyzed. Finally, the similarities and differences of the conventional 2D and the new 3D formulations of partial polarization are briefly discussed.
