| Abstract: | In this paper,bend line defects are introduced in two-dimensional magnonic crystals.Band structures and field distributions of magnetization are calculated by using the plane-wave expansion method with the supper-cell approximation,and then the properties of defect states of bend line defects in two-dimensional magnonic crystals are investigated. |
