| 摘 要： | 本文采用平面波展开法数值计算了由铁圆柱分别按正方排列、三角排列以及六角排列在氧化铕基底材料中构成的二维磁振子晶体带结构,讨论了散射体的不同排列方式对磁振子晶体带隙结构的影响.计算结果表明,三角排列散射体的磁振子晶体能够获得最大的自旋波带隙结构.

| Abstract: | 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. |
