  Using a microscopic transport model we investigate the evolution of conical
structures originating from the supersonic projectile moving through the hot
matter of ultrarelativistic particles. Using different scenarios for the
interaction between projectile and matter, and different transport properties
of the matter, we study the formation and structure of Mach cones. Especially,
a dependence of the Mach cone angle on the details and rate of the energy
deposition from projectile to the matter is investigated. Furthermore, the
two-particle correlations extracted from the numerical calculations are
compared to an analytical approximation. We find that the propagation of a high
energetic particle through the matter does not lead to the appearance of a
double peak structure as observed in the ultrarelativistic heavy-ion collision
experiments. The reason is the strongly forward-peaked energy and momentum
deposition in the head shock region. In addition, by adjusting the cross
section we investigate the influence of the viscosity to the structure of Mach
cones. A clear and unavoidable smearing of the profile depending on a finite
ratio of shear viscosity to entropy density is clearly visible.
