The paper presents the results of numerical modeling of air-coupled ultrasonic Lamb waves excitation in an isotropic single layer thin plastic film.
The method is applied in the case of non-destructive testing and evaluation (NDT & NDE) of plate structures. Usually air-coupled technique has a very serious drawback: global insertion losses for an entire system may be dB typically, so Cited by: 5.

Jan 30, · The Influence of Finite-size Sources in Acousto-ultrasonics. NASA Technical Reports Server (NTRS) An asymmetric actuating structure generating negligible influence on the supporting base for high performance scanning probe microscopies is proposed in this paper.
The actuator structure consists of two piezostacks, one is used for actuating. Full text of "NASA Technical Reports Server (NTRS) Third NASA Advanced Composites Technology Conference, volume 1, part 2" See other formats.
The articles are written in an informal style, from mathematical philosophy to the description of the development of ideas, personal memories and give a unique account of personal meetings with famous representatives of twentieth century mathematics who exerted great influence in its development.
This book will be of great interest to. Piezoelectric Materials and Devices- Practice and Applications. cro-valves [4, 5], devices for generating and detecting sound  and implantable medical de vices . They may also be useful in other applications such as microwave micro-switches where it is important to.
Different setups are shown that minimize the influence of physical bulk effects on the sensor signal, e.g. salt content and viscosity. The choice of materials which can be used for sensible surfaces are presented, enabling the development of completely new coupling chemistries.
Finally, the advantages compared to other biosensor technologies.
