Title: Air-coupled method to investigate the lowest-order antisymmetric Lamb mode in stubbed and air-drilled phononic plates

Abstract

In this work, we applied a robust and fully air-coupled method to investigate the propagation of the lowest-order antisymmetric Lamb (A{sub 0}) mode in both a stubbed and an air-drilled phononic-crystal (PC) plate. By measuring simply the radiative acoustic waves of A{sub 0} mode close to the plate surface, we observed the band gaps for the stubbed PC plate caused by either the local resonance or the Bragg scattering, in frequency ranges in good agreement with theoretical predictions. We measured then the complete band gap of A{sub 0} mode for the air-drilled PC plate, in good agreement with the band structures. Finally, we compared the measurements made using the air-coupled method with those obtained by the laser ultrasonic technique.

  • An ultrasonic nondestructive evaluation technique of the layer thickness in human teeth is proposed using a leaky Lamb wave device with two arch-shaped interdigital transducers, operating at a plate/water interface. The use of a higher-order-mode leaky Lamb wave with a phase velocity higher than the longitudinal wave velocity in the human tooth is essential to detect reflected ultrasound beams from the tooth section The layer thickness of dentin, estimated from the measured time interval between two reflected echoes, is in good agreement with the optically measured data.
  • This work deals with an analytical and numerical study of the focusing of the lowest order anti-symmetric Lamb wave in gradient index phononic crystals. Computing the ray trajectories of the elastic beam allowed us to analyze the lateral dimensions and shape of the focus, either in the inner or behind the phononic crystal-based acoustic lenses, for frequencies within a broad range in the first band. We analyzed and discussed the focusing behaviors inside the acoustic lenses where the focalization at sub-wavelength scale was achieved. The focalization behind the gradient index phononic crystal is shown to be efficient as well: wemore » report on FMHM = 0.63╬╗ at 11MHz.« less
  • The ground-state energy of solid hydrogen and deuterium is calculated by means of a modified variational lowest order constrained-variation (LOCV) method. Both fcc and hcp H/sub 2/ and D/sub 2/ are considered, and the calculations are done for five different two-body potentials. For solid H/sub 2/ we obtain theoretical results for the ground-state binding energy per particle from -74.9 K at an equilibrium particle density of 0.700 sigma/sup -3/ or a molar volume of 22.3 cm/sup 3//mole to -91.3 K at a particle density of 0.725 sigma/sup -3/ or a molar volume of 21.5 cm/sup 3//mole, where sigma = 2.958more » A. The corresponding experimental result is -92.3 K at a particle density of 0.688 sigma/sup -3/ or a molar volume of 22.7 cm/sup 3//mole. For solid D/sub 2/ we obtain theoretical results for the ground-state binding energy per particle from -125.7 K at an equilibrium particle density of 0.830 sigma/sup -3/ or a molar volume of 18.8 cm/sup 3//mole to -140.1 K at a particle density of 0.843 sigma/sup -3/ or a molar volume of 18.5 cm/sup 3//mole. The corresponding experimental result is -137.9 K at a particle density of 0.797 sigma/sup -3/ or a molar volume of 19.6 cm/sup 3//mole.« less
