中文摘要：

利用平面波展开法计算了一维线性函数磁振子晶体和常规磁振子晶体自旋波的带结构.计算结果表明,函数磁振子晶体与常规磁振子晶体的带结构有明显区别,且一维线性函数磁振子晶体带隙的数目和宽度均随磁参数的变化而发生改变.因此,可以通过改变参数对一维函数磁振子晶体的带结构进行调节.

英文摘要：

Using the plane wave expansion method,the one-dimensional linear function of magnonic crystals and the band structure of conventional magnonic crystals of spin waves have been calculated. The calculation results show that the structure function of magnonie crystals and conventional magnonic crystals are obviously different,and the number and width of the band of one-dimensional linear function changes with the magnonic parameters change. Therefore,by changing the parameters, the function of one- dimensional magnonic crystals with structural can be adjusted.
