  Active microrheology is a valuable tool to determine viscoelastic properties
of polymer networks. Observing the beads response to the excitation of a
reference leads to dynamic and morphological information of the material. In
this work we present an expansion of the well-known active two-point
microrheology. By measuring the response of multiple particles in the
viscoelastic medium in response to the excitation of a reference particle we
are able to determine the force propagation in the polymer network.
