Published: July 2023

Electric and magnetic energy densities as well as energy flux (Poynting vector) for radial variant vector beam focusing through a dielectric interface is analyzed numerically based on vector diffraction theory. The electric and magnetic energy densities are tailored by properly manipulating the radial as well as initial phases to generates novel focal patterns in the focal area. These peculiar properties may find applications in fields such as optical trapping, optical recording, magnetic recording, and magnetic resonance microscopy and semiconductor inspection.
