Abstract
We present results from a three-dimensional particle-in-cell simulation of plasma turbulence, resembling the plasma conditions found at kinetic scales of the solar wind. The spectral properties of the turbulence in the subion range are consistent with theoretical expectations for kinetic Alfvén waves. Furthermore, we calculate the local anisotropy, defined by the relation k∥(k⊥), where k∥ is a characteristic wave number along the local mean magnetic field at perpendicular scale l⊥∼1/k⊥. The subion range anisotropy is scale dependent with k∥
