In this work, special\n\t\t\t\t\tattention is paid to the distribution of internal energy flows\n\t\t\t\t\tdescribed by the transverse Poynting momentum (TPM) components. This\n\t\t\t\t\tapproach discloses additional polarization-dependent features of the\n\t\t\t\t\tvector beam transformations; in application to the edge diffraction of\n\t\t\t\t\ta circularly polarized (CP) Gaussian beam, it reveals the\n\t\t\t\t\thelicity-dependent asymmetry of the diffracted-field TPM profile\n\t\t\t\t\tcharacterized by the shifts of the TPM singularity, maximum, etc.\n\t\t\t\t\tThese phenomena are confirmed experimentally and interpreted in terms\n\t\t\t\t\tof the spin-orbit interaction (SOI) and spin Hall effect of light.
