In this paper, band structures of two-dimensional magnonic crystals with square arrangement, triangle arrangement and honeycomb arrangement of Fe cylinders in matrix of EuO are calculated by the plane-wave expansion method. And the effects of arrangements of scatterers on the band gaps of two-dimensional magnonic crystals are discussed. The numerical results show that the gap of the triangle arrangement is the largest in the above three lattices.
