Title: Confinement of magnetostatic forward volume waves in two-dimensional magnonic crystals with line defects

The mode patterns of magnetostatic forward volume waves (MSFVWs) propagating in two-dimensional magnonic crystals with line defects via periodic variation in thickness of square lattice in a yttrium iron garnet thin film are reported. The theoretical approach based on Walker's equation was employed to analyze the confinement of MSFVWs in the line defects. A good agreement between the theoretical predictions and the experimental results was obtained.
