Spectral mode decomposition of propagating wave in five-coupled bistable oscillators

This study investigates the dynamics of propagating waves in five-coupled bistable oscillators using the exact dynamic mode decomposition (DMD) method. The results show that for weakly-nonlinear oscillators, the DMD method effectively captures the wave characteristics and aligns well with the theoretical predictions. In contrast, for strongly-nonlinear oscillators, while there are challenges due to the localized nature of the waves, the method is still capable of detecting dominant frequency peaks.
