We study the effect of focusing of the radially and azimuthally polarizedvector beams on the spin angular momentum (SAM) density and Poynting vector ofscattered waves from a Mie particle. Remarkably, the study reveals that the SAMdensity of the scattered field is solely transverse in nature for radially andazimuthally polarized incident vector beams; however the Poynting vector showsusual longitudinal character. We also demonstrate that the transverse SAMdensity can further be tuned with wavelength and focusing of the incident beamby exploiting the interference of different scattering modes. These results maystimulate further experimental technique of detecting the transverse spin andBelinfante's spin-momentum densities.
