FIG. 1.

Frequency response curve of a harmonic cantilever with an attached concentrated mass (solid line) is compared with that of an uniform cantilever (dotted line). [The frequency and the vibration magnitude are normalized by the fundamental natural frequency and the amplitude at low frequency , respectively. , , the quality factor .] Arrows indicate the 5th and 15th harmonics of the fundamental frequency which are significantly enhanced by the second and third eigenmodes of the harmonic cantilever, respectively.
