Book excerpt: Ultrasonics International 91 is a documentation of conference proceedings that discusses the status and future of acoustic microscopy and its application to materials research, especially focusing on its quantitative analyses. Acoustic microscopy, using focused waves, has been receiving increased attention as a technology applicable to materials characterization at the microscopic scale. In acoustic microscopy, the excitation and propagation of leaky surface acoustic waves (LSAWs) in the environment of the coupling liquid at the solid specimens are observed. Three types of the systems have been developed: point-focus-beam (PFB), line-focus-beam (LFB), and directional PFB acoustic microscopes. In this paper, a brief history of the practical developments is first presented, followed by LFB acoustic microscopy for quantitative material characterization and some applications concerned with characterization of elastic anisotropy and inhomogeneity of electronic materials, such as LiNb03 and LiTa03 single crystals, and thin-film characterization. This book gives a comprehensive account of the majority of the oral and poster contributions made during the conference, and makes a valuable addition to a student or researchers' ultrasonic literature.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains 17 invited papers and 80 communicated papers presented at the International Symposium on Physical Acoustics, held at the University Campus of Kortrijk, Belgium, from 19-22 June 1990. The twenty-fifth anniversary of the Campus was celebrated with special activi ties such as concerts, exhibitions and scientific meetings. This symposium was a part of the celebration. The 120 participants came from 18 different countries. Among the largest groups we mention 32 French contributions and 19 contributions from the U.S.S.R. We especially thank Prof. V.V. Proklov from Moscow and Prof. S.V. Kulakov from Leningrad who helped us with the distribution of invitations in the U.S.S.R. We also thank Prof. G. Quentin and Ir B. Poiree from Paris who endeav oured to inform all French acousticians. We thank all the lecturers for their effort in producing the material for the book in time. The invited lectures have been collected and retyped by Prof. M. Breazeale (U.S.A.), while the contributed papers were collec ted by Prof. O. Leroy and retyped in Belgium. The first 200 pages of the book comprise the invited lectures, not classified by topic, but are in alphabetical order with reference to the first author. The second part of the book contains the contributed papers and posters also classified in alphabetical order according to the first author.

Download or read book Light Diffraction by Ultrasonic Waves as a Multiple Scattering Process written by H. V. Hance and published by . This book was released on 1964 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of light diffraction by ultrasonic waves has been studied extensively in the past, but quantitative investigations have been limited in scope, probably because of computational difficulties. Recently, there has been developed a method of analysis that allows numerical computation for arbitrarily specified conditions to be carried out on a digital computer. This method, which employs approximate theory and an iterative process, is used in this study to investigate the ultrasonic diffraction effect over a wide range of conditions. When the ratio of light wavelength to ultrasonic wavelength is small compared to unity, the theoretical development on which this numerical analysis is based shows that the intensities in the various diffraction orders are determined by three nondimensional parameters. These parameters are related to three physical parameters of the ultrasonic beam-wavelength, intensity, and width-and two physical parameters of the light beam-wavelength and incidence angle. Special attention is given to the variation of diffracted-beam intensity with variation of the parameters about values that produce strong Bragg scattering into the -1st order. These conditions are of particular interest because of the possibility of diverting all incident-beam power into one diffraction order under control of the ultrasonic beam. In addition, the conditions required for strong Bragg diffraction into the -2nd order are determined. (Author).

This book was released on 1968 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report, a method is developed for the quantitative evaluation of the effects of large irregularities or obstacles on the propagation of a radio wave. The fundamental tool used is Keller's "geometrical theory of diffraction." In contrast to previous methods for treating this problem, the one proposed here is not limited by 1) the type of terrain, 2) the polarization of the transmitting antenna, 3) the radiation pattern of the antenna, and 4) the frequency of the antenna (provided ka>̲ 5.0, where a is the characteristic dimension of the diffracting obstacle). A numerical example showing the antenna pattern behind a hemispherical hill illustrates the application of the theory.

Download or read book Imaging of Finite Amplitude Ultrasonic Waves by Bragg Diffraction of Light written by Franklin Douglass Martin and published by . This book was released on 1971 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light which has undergone Bragg diffraction by Ultrasonic waves produces diffraction orders which actually contain images of the ultrasonic wavefront. This report includes observation and discussion of this first-order imaging. In addition, this report includes observation and discussion of higher order imaging which occurs when ultrasonic waves of finite amplitude are used. The conditions for dominance of Bragg diffraction over 'regular' diffraction are examined in relation to this higher order imaging, which is characterized by the appearance of multiple images in the higher diffraction orders. A transmission filter plate placed in the ultrasonic beam reveals that in addition to scattering and rescattering of light from the fundamental ultrasonic frequency, scattering of light from the second harmonic of the ultrasonic wave can be observed. The theory of Bragg diffraction of light by ultrasonic waves has been used to account for experimental observations of first-order imaging. This theory has been extended to account for experimental observations in higher order imaging by relating it to multiple scattering of the light by the ultrasonic wave. (Author).
Download or read book Physics Project Lab written by Paul Gluck and published by Oxford University Press. This book was released on 2015 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of many years of experience of the authors in guiding physics projects. It aims to satisfy a deeply felt need to involve students and their instructors in extended experimental investigations of physical phenomena. Over fifty extended projects are described in detail, at various levels of sophistication, aimed at both the advanced high school, as well as first and second year undergraduate physics students, and their instructors. Carrying out these projects may take anything from a few days to several weeks, and in some cases months. Each project description starts with a summary of theoretical background, proceeds to outline goals and possible avenues of exploration, suggests needed instrumentation, experimental setup and data analysis, and presents typical results which can serve as guidelines for the beginner researcher. Separate parts are devoted to mechanics, electromagnetism, acoustics, optics, liquids, and thermal physics. An additional appendix suggests twenty further ideas for projects, giving a very brief description for each and providing references for pursuing them in detail. We also suggest a useful library of basic texts for each of the topics treated in the various parts.
