Mason retired from Columbia in 1977. Bringing together the fields of thermodynamics, kinetic theory, fluid mechanics, and theoretical acoustics, plus a wealth of information about practical instruments, this book represents an essential reference on the design and execution of valuable experiments in fluid metrology and physical acoustics. Bateman , Journal of the Acoustical Society of America, vol. They can be made with much sharper than can be achieved with conventional. Sc in electrical engineering from the in 1921. Mason around 1966 Warren Perry Mason September 28, 1900 — August 23, 1986 was an American electrical engineer and physicist at. Mason was president of the in 1956.
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 final chapter describes imaging with optically generated thermal waves. The selection is a valuable reference for readers interested in physical acoustics. His work included , , crystals and ceramics, , , , bonding to , , and. This work helped quantify the theory of in semiconductors. Other fields of study included and , crystals, underwater sound , bonding of metals to metals and , physics of wear, semiconductor , , and of solids and liquids. Mason invented a new type of mechanical filter, the consisting of of crystals, which became the standard form of filtering on these systems.
Physicists and researchers will find this book useful. Organized into nine chapters, this volume starts with an overview of the transmission of sound waves in semiconducting crystals that are piezoelectric. 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. Chapter 4 tackles the ways of predicting diffraction loss and phase distortion, and discusses the alleviation of diffraction effects by acoustic beam shaping, material selection and orientation, and alterations in the transducer structure. His name led his colleagues to compare him to the fictional character.
In this work, Mason pioneered the use of the to describe acoustic filters. Register a Free 1 month Trial Account. Mason went with Bell Labs and remained there for his entire career. However, it became unnecessary once quartz was possible. Double Quantum Detection of Phonons X. Both his mother and father graduated from the around 1890. Register a Free 1 month Trial Account.
The selection first tackles wave propagation in fluids and normal solids and guided wave propagation in elongated cylinders and plates. They had a daughter, Penelope E. The selection first tackles wave propagation in fluids and normal solids and guided wave propagation in elongated cylinders and plates. A graduate of , he had a prolific output, publishing four books and nearly a hundred papers. From 1948, Mason was head of the Mechanics Research Department. Their plane crash-landed near where several people died, including the pilot who re-entered the burning plane in an attempt to rescue a passenger.
This text then describes acoustic and plasma waves in ionized gases wherein oscillations are subject to hydrodynamic as well as electromagnetic forces. Bateman measured attenuation and velocity changes in and. The next chapter discusses the use of ultrasound in investigating Landau quantum oscillations in the presence of a magnetic field and their relation to the strain dependence of the Fermi surface of metals. The third chapter focuses on the ultrasonic measurements that are made by pulsing methods with velocities obtained through phase comparison methods and attenuations obtained through comparing pulse heights for successive reflections. In Chapter 4, methods for measuring the properties of solids and liquids at very high pressures are described. Subsequent chapters focus on electron-acoustic imaging of solids; the theory of photothermal and photoacoustic effects in condensed matter; the use of photoacoustics to study the vibrational relaxation of molecules; and analytical applications of photoacoustic spectroscopy to condensed phase substances.
With the advent of modern instrumentation, it is now possible to determine the speed and absorption of sound with extremely high precision and, through the dependence of those quantities on variables like temperature, pressure, and frequency to gain a sensitive measure of one or more properties of fluid. 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 final chapter examines how measurements can delineate the Fermi surface of monovalent metals. Other chapters consider the amplification of acoustic waves in semiconductors by the application of an electric field. Bömmel found experimental evidence for electron-phonon coupling in pure samples of lead and tin. Mason was known for his peculiar habit of pacing in place while thinking, which he apparently did to avoid missing experimental results as they happened.
New Approach to Vapor Deposition V. By 1983, Bell Labs had reached a total of twenty thousand patents. Chapter 1 describes the principles and applications of a tool for investigating phonons in dielectric crystals, the spin phonon spectrometer. Thermoelastic generation at a free surface is considered, along with the effect of material ablation and the effect of surface modification by a thin liquid coating or constraining solid layer. Many of Mason's inventions in electronics are still widely used by modern circuit designers.
A large part of his work concerned , not only in the electrical domain, but also in the mechanical and acoustic domains. This was the most patents that anyone at Bell Labs had ever been issued. Mason's inventions in electronics are still widely used. 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. D in 1928, both in physics.
