• By means of the particle simulation, we study the excitation mechanism of low frequency (0.01-0.05Hz) upstream hydromagnetic waves. Initially, we observe excitation of the right-hand polarized waves propagating parallel to the field-aligned ion beam, which is given as the free energy source. In the nonlinear stage, we observed the phase space bunching of beam ions by the excited waves. We apply this bunching effect to the explanation of 'gyrophased bunched' ions observed in the foreshock region.
