Abstract: New solutions of the parabolic equation describing vector rotating paraxial TM Arnaud beams with complex astigmatism are investigated. Permissible values of free parameters for which Arnaud beams carry finite power are established. Explicit expressions describing the energy and polarization properties of vector Arnaud beams with complex astigmatism are proposed. Graphical modeling and corresponding analysis of polarization ellipses, intensity and transverse energy fluxes of vector paraxial Arnaud beams with homogeneous and inhomogeneous (TM modes) polarization are carried out.

Keywords: polarization, vector beams, rotating beams, Gaussian beams, complex astigmatism, TM-modes, transverse energy fluxes.
