Wiring and signal modulation techniques for spin waves are essential to achieve high performance in spin-wave devices as the next generation of information processing devices. In this work, two-dimensional magnonic crystals that were able to control the propagation of spin waves were designed using the finite integration technique. A structure in which a band gap of two-dimensional magnonic crystals could be observed was obtained, and the shift of the band gap with variation in the incident angle of the spin waves was obtained.
