Analytical expressions which determine the probability of sputtered atom escaping from a cylindrical cavity and a rectangular trench on the target surface bombarded by an ion beam are obtained for sputtered atoms cosine and over-cosine angle distributions. It is shown that the sputtering yield can be substantially reduced by creation a relief of cylindrical cavities ...

We study analytically and numerically the distribution of granular temperatures in granular mixtures for
different dissipation mechanisms of inelastic inter-particle collisions. Both driven and force-free systems
are analyzed. We demonstrate that the simplified model of a constant restitution coefficient fails to
predict even qualitatively a granular temperature distribution in a homogeneous cooling state. At the
same time we reveal ...
