Based on vectorial Debyetheory, the tight focusing properties of partially coherent and circularly polarized vortex beams are investigated.

The calculation process of the method is independent of size parameters, and it is more stable and faster than the traditional methods based on Lorenz-Mie theory or Debye-series expansion.
