Radial similarity measures for vectorial structured light

Properties of a harmonic electromagnetic beam revealed by its polarization-orbitalization tensor (POT) at two radii are discussed. In particular, the polarization and orbitalization projections of the POT are extended to two radii, and various quantities distinguishing radial similarity and mixing among the components of the POT are examined. The results are demonstrated with a beam composed of Laguerre-Gaussian modes.
