Book Description
Physical Acoustics: Principles and Methods, Volume IX includes four chapters that are device-oriented and devoted to understanding electron drag stresses on dislocations and difference in flow stress between the normal and superconducting states of Type I and Type II superconductors. Chapter 1 explains that when a dislocation moves through a crystal, it gives up energy to the medium either through a nonlinear motion over a dynamic Peierls barrier or through conversion of energy by scattering of electrons or phonons, which takes place with an energy loss proportional to the velocity. The next chapter discusses the propagation of ultrasonic surface waves in thin layers. The thin layer confines a surface wave laterally, providing a desired dispersion characteristic, acting as part of a transducer for generating surface waves, or providing an interaction region for other phenomena. Chapter 3 deals with a generation of solid state control elements that utilize the inverse piezoelectric effect. The last chapter provides approximate equations for coupled resonators and methods for accurately controlling the band frequency and bandwidth. This book is a useful reference for students and physicists working on physical acoustics.

Book Description
AN AUTHORITATIIVE, UP-TO-DATE INTRODUCTION TO PHYSICAL ACOUSTICS Easy to read and understand, Fundamentals of Physical Acoustics fills a long-standing need for an acoustics text that challenges but does not overpower graduate students in engineering and physics. Mathematical results and physical explanations go hand in hand, and a unique feature of the book is the balance it strikes between time-domain and frequency-domain presentations. Fundamentals of Physical Acoustics is intended for a two-semester, first-year graduate course, but is also suitable for advanced undergraduates. Emphasis on plane waves in the first part of the book keeps the mathematics simple yet accommodates a broad range of topics: propagation, reflection and transmission, normal modes and simple waveguides for rectilinear geometries, horns, inhomogeneous media, and sound absorption and dispersion. The second part of the book is devoted to a more rigorous development of the wave equation, spherical and cylindrical waves (including the more advanced mathematics required), advanced waveguides, baffled piston radiation, diffraction (treated in the time domain), and arrays. Applications and examples are drawn from: * Atmospheric acoustics * Noise control * Underwater acoustics * Engineering acoustics * Acoustical measurements Supplemented with more than 300 graphs and figures as well as copious end-of-chapter problems, Fundamentals of Physical Acoustics is also an excellent professional reference for engineers and scientists.

Book Description
Physical Acoustics: Principles and Methods, Volume l—Part A focuses on high frequency sound waves in gases, liquids, and solids that have been proven as powerful tools in analyzing the molecular, defect, domain wall, and other types of motions. The selection first tackles wave propagation in fluids and normal solids and guided wave propagation in elongated cylinders and plates. Discussions focus on fundamentals of continuum mechanics; small-amplitude waves in a linear viscoelastic medium; representation of oscillations and waves; and special effects associated with guided elastic waves in plates and cylinders. The book also touches on piezoelectric and piezomagnetic materials and their functions in transducers, including polycrystalline ferroelectrics, equations of the piezoelectric medium, and equivalent circuits. The publication takes a look at ultrasonic methods for measuring the mechanical properties of liquids and solids and the use of piezoelectric crystals and mechanical resonators in filters and oscillators. The text then ponders on guided wave ultrasonic delay lines and multiple reflection ultrasonic delay lines, as well as transmission of sound waves in solids, torsional mode delay lines, and transducer considerations. The selection is a valuable reference for readers interested in physical acoustics.

Book Description
Physical Acoustics: Principles and Methods, Volume XIV is a five-chapter text that covers significant studies on acoustic microscopy, sound propagation in liquid crystals, ultrasonic transducers, and ultrasonic flowmeters. The opening chapter discusses techniques of acoustic microscopy, aberration and resolution performance, acoustic lens transfer functions, antireflection coatings, and both transmission and reflection acoustic microscopy. The following chapter deals with the applications to the states called liquid crystals or anisotropic liquids, states in which the material flows but yet has a long-range order that makes it macroscopically anisotropic. The third chapter focuses on the principles and practical applications of electromagnetic transducers for both surface waves and bulk waves. The fourth chapter surveys first the characterization of ultrasonic transducers for materials testing and then compares actual responses to those of an ""ideal"" transducer, elaborating on the many important factors that affect the results obtained with an ultrasonic testing system. The final chapter explains the principles underlying ultrasonic measurements of flow, specifically covering eight different categories of ultrasonic flow measurement principles and their industrial applications indicated. This book will be of great value to researchers in their fields of electronics technology and applied and engineering mechanics.
