Based on the accurate expression of light intensity of nonparaxial vector beams at the transverse plane and the vectorial second order moment theory of light beam propagationby applying rigorous vectorial diffraction theory of the angular spectrum representationthe nonparaxial propagation of any vectorial diffraction beam has been systemically investigatedthe integral expressions of beam widthtransversal divergence angle have been presentedand the divergent characteristic of the second order moment of nonparaxial vector beams has been demonstrated. The definitions of beam widthtransversal divergence angle of non-paraxial vector beams and some related problems have been discussed.
