49], it was shown that not only a wider bandwidth but also a better performance could be obtained by the monostable configuration, as compared to the linear configuration (with stationary magnets removed), as shown in Fig. 32. This might be due to the change of damping due to the magnets used in the experiment [20, 22], while a constant damping was used in the analysis by Ramlan et al. [49]. Previous monostable designs have a larger bandwidth due to the shift in the resonant frequency. This nonlinear advantage if the high-energy attractor regime 46 L.
