二维磁振子晶体中点缺陷模的耦合性质研究
Coupling characteristics of point defect modes in two-dimensional magnonic crystals
摘要
Abstract
Using the plane-wave expansion method under supercell approximation, band structures of spin waves propagating in two- dimensional magnonic crystals with coupling multi-point defects and magnetization field distributions of some defect modes are calculated. The results indicate that the energies of point defect modes can couple each other, and propagate along the direction of the multi-point defects in these structures. Utilizing the coupling characteristics of defect modes, two-dimensional magnonic crystals can be used as the fabricating materials of spin-wave waveguides.关键词
