Abstract: The new solutions of the Helmholtz equation describing nondiffracting nonparaxial shifted Bessel wave fields with various azimuthal dependences are offered. They are characterised by five free parametres. Pictorial modelling of such beams is fulfilled. The dependences of the patterns of intensity of Bessel fields on the free parametres are analysed.

Keywords: beams, Bessel beams, azimuthal dependence, shifted fields, Bessel fields.
