Dual Band Magnonic Crystals: Model System and Basic Spin Wave Dynamics

Figure 1

Primitive cell of the 2D magnonic crystal used for calculations. The angle is the direction at which the external magnetic field is applied. Distance between the small squares is  nm. This cell is unitary only for the secondary sublattice (). The red line square is the ideal unitary primitive cell of the primary sublattice (which was however not directly used in the calculations).
