However, the plasmonic resonance mediating the transmission through the slit will lead to nonlinear dependence of transmission on slit width (as shown in Figure 2e), allowing the alternate-slit-width structure to improve transduction of the in-plane mechanical mode, and precludes the observed effects being due to a purely geometric modulation of the transmitted light by the beams' motion.
The first objective function comprises the damping factor of lightly damped electro-mechanical modes and the second one includes the damping ratio of these modes.
The poorly damped electrical and mechanical modes of the system are identified, and the effects of system parameters, and speed/rotor controllers on these modes are investigated by modal and sensitivity analyses.
A unique array of predatory strategies occur among snakes, ranging from mechanical modes of constriction and jaw-holding in non-venomous snakes, to a chemical means, venom, for quickly dispatching prey.
Further, mechanical modes were applied to help regulate stent designs.
The sampling rate of the displacement sensors, 1.5 kHz, is well above the frequencies of the expected mechanical modes.
The peaks are related to the thermal motion of individual mechanical modes.
Interestingly, only five resonant mechanical modes are observed in the spectrum, with varying amplitude.
We also observe a nonavoided crossing, suggesting these mechanical modes are related to nonadjacent beams.
By tuning the gap width, the plasmonic resonances are tuned, allowing simultaneous parallel transduction of the mechanical modes of all beams.
The performance of a feedback-controlled piezoelectric tube scanner is limited by its inherent nonlinear properties such as hysteresis and creep, its mechanical resonance modes and its displacement sensor bandwidth and associated noise properties.
