- Additional information
- An innovative numerical method is developed for efficient computation of 3D band structures of phononic crystals. It uses only one fictitious node to tackle instability problems caused by calculation of derivatives of the wave pressure. The effectiveness and efficiency of the method has been validated by a few examples of sound pressure wave propagation. The new method allows for fast calculation of bandgaps of periodic structures or metamaterials, which opens the possibility of optimising structural design of soundproofing walls, invisible cloths and aeroplanes, to name a few.
