The expressions for calculation of phase function (or element of scattering matrix f11) by optically "soft" ( Ѕm - 1Ѕ << 1, where m = n + ic is a relative refractive index of cylinder) circular finite cylinder for incident light in the direction at any angle to the axis of cylinder in Wentzel - Kramers - Brillouin (WKB) in scalar form approximation are obtained. Numerical results of light scattering phase function for infinitely long cylinder (rigorous solution) and for finite circular cylinders in WKB approximation are compared.
