Forward scattering is the scattering of photons (particles of light
or other forms of electromagnetic radiation)
by a medium in such a way that most of the photons end up traveling in roughly
the direction they started. More generally, it is scattering in which the
angle between the initial and final directions of motion of the scattered
particles is less than 90°.

Forward scattering is always accompanied by some backscattering (scattering
in a generally backward direction), the proportion of the former increasing
with particle size.
