1486. Abstract
... Stress-Dependent Complementary Variations in P- and S-Wave Velocities for Rocks Containing High-Compliance Porosity: an Effective-Medium Model and Comparison with Experiments . ... A 3D effective-medium model describing variation in rock elastic moduli due to presence of high-compliant defects is considered. ... The ratio of the normal-to-shear compliance of the defects was determined for different rock samples. The results confirmed that, in saturated rocks, defect’s shear compliance dominates. ...

1496. Abstract (Invited)
... Supercritical Parametric Phase Conjugation of Ultrasound Waves. Application in Nonlinear Acoustic Imaging . ... Parametric wave phase conjugation (WPC) is a new tool for ultrasonic engineering providing time reversal transformation of acoustic beams with giant amplification [1]. Application of parametric WPC for compensation of phase distortions in linear acoustic imaging was already demonstrated. ... Generally speaking, amplification breaks time reversal invariance of a wave field. ...

1497. Abstract
... Superharmonic Tissue Imaging . ... Medical imaging has recently seen improvement in image quality with second-harmonic (2H) tissue imaging. This was attributed to less reverberations and haze and better sidelobe suppression compared to fundamental imaging. ... Moreover, SH imaging does not suffer from the resolution-sensitivity trade-off and since it operates over a wide frequency band, the axial resolution is further improved. ...

... Surface Acoustic Wave Propagation in the Presence of Strong External Field . ... The paper deals with the change of small amplitude surface acoustic wave (SAW) velocity in the presence of strong generalised field, for example the electric one [1]. ... As a result of computational procedure the sensitivity of SAW velocity to the external field is found. ... 1] Zelenka, J., Kosek, M.: Properties of surface acoustic wave devices under strong external fields. ...

... Surface Mapping of Subharmonic Generated Modes in Finite Piezoelectric Structures . A.Alippi, M.Angelici, A.Bettucci, M.Germano (Department of Energetics, University Rome "La Sapienza", Rome, Italy) . ... Finite piezoceramic transducers vibrating nonlinearly are studied, both experimentally and theoretically. When driven by high voltages, not only higher order harmonics are generated, but the rising of fractional harmonic components is observed, this results being a threshold phenomenon. ...

1500. Abstract
... Surface Shear Waves in Homogeneous Gradient-Elastic Half Space with Surface Energy . ... It was shown that shear-horizontal waves (i.e. not plane shear wave motions with amplitude, which decreases exponentially with the increase of the distance from free surface) could exist in homogeneous half space, if the problem is analyzed in a framework of the gradient elasticity theory, generalized so that the surface energy is taken into account. ...
