Abstract
Interplanetary dust particles are different in size, chemical composition, shape and physical-optical properties. The light scattering by such particles predetermines changes of their motion in the space. This fact is expressed by well-known radiation pressure, which was notoriously based on assumption of very simple models of particle shape. Mie theory is for example applicable when approximate the cosmic dust grains by spheres. The only forward and backward scattering efficiencies are important in this case. However, any irregularity of the particle shape will produce certain momentum in perpendicular projections to the direction of light propagation. This may be caused also by inhomogeneity of particle chemical composition (or particle density) (Eremin and Ivakhnenko, 1998). Particle shape specificity (cavities,...) plays dominant role in formation of light scattering diagram (Mishchenko et al., 2000).
