Abstract
The waveguide properties of spin waves through line defects in two-dimensional magnonic crystals are investigated by numerical calculating band structures and magnetization-field distributions of the defect modes. The results show that the spin waves are very well localized in the line defects, and the size of the defect bodies has an obvious influence on the defect modes existing in the frequency regime of the gap. It will provide us a theoretical foundation in the designing of spin-wave waveguides with different shapes.
