Nonlinear dynamics of flexural wave turbulence.

The Kolmogorov-Zakharov spectrum predicted by the weak turbulence theory remains elusive for wave turbulence of flexural waves at the surface of a thin elastic plate. We report a direct measurement of the nonlinear time scale T(NL) related to energy transfer between waves. This time scale is extracted from the space-time measurement of the deformation of the plate by studying the temporal dynam...

A Protein Concentration Measurement System Using a Flexural Plate-Wave Frequency-Shift Readout Technique

A protein concentration measurement system with two-port flexural plate-wave (FPW) biosensors using a frequency-shift readout technique is presented in this paper. The proposed frequency-shift readout method employs a peak detecting scheme to measure the amount of resonant frequency shift. The proposed system is composed of a linear frequency generator, a pair of peak detectors, two registers, ...

Acoustic and flexural wave scattering from a three-member junction

A three-member junction is formed by a pair of semi-infinite plates in contact with fluid on one side and a mechanical structure on the other. The latter is described by an impedance matrix. The excitation is either a straight crested flexural wave traveling on one of the fluid-loaded plates and obliquely incident on the line junction, or an acoustic plane-wave incident from any direction in th...

Non-reciprocal flexural wave propagation in a modulated metabeam

Flexural wave propagation in an Euler–Bernoulli beam coupled to a set of spring–mass resonators is investigated in the presence of a pump wave in the form of a space–time modulation of the beamresonators coupling stiffness. A phase matching condition implies then that waves incident along or against the pump wave behave differently and gives rise in select frequency bands to one-way blocking an...

Flexural Wave Propagation in Slowly Varying Random Waveguides Using a Finite Element Approach

This work investigates structural wave propagation in waveguides with randomly varying properties along the axis of propagation, specifically when the properties vary slowly enough such that there is negligible backscattering. Wave-based methods are typically applied to homogeneous waveguides but the WKB (after Wentzel, Kramers and Brillouin) approximation can be used to find a suitable general...
