Download or read book Some Recent Advances in Microwave Phonon Generation and Detection with Applications to the Study of Phonon lattice Interactions in Dielectric Materials written by John DE Klerk and published by . This book was released on 1964 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some recent advances in phonon generation and detection in the gigacycle region are described. The technique, as applied to quartz, has been extended to non-piezoelectric materials by the use of vapor deposited thin film piezoelectric transducers. Attenuation measurements in quartz, MgO, TiO2 and Al2O3 are described and discussed. A theory for the behavior of attenuation as a function of temperature is also given. (Author).

This book was released on 1964 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design procedure and considerations for a tunable resonant coaxial microwave cavity are discussed. The design of a practical cavity for use between 1 and 8 Kmc/sec is given. A technique for producing exponentially decaying echo envelops is described. A method of accurately measuring small changes in low attenuation rates is given. Measurements made in quartz at low temperatures and at 1000 mc/sec are described. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonic Methods in Solid State Physics is devoted to studies of energy loss and velocity of ultrasonic waves which have a bearing on present-day problems in solid-state physics. The discussion is particularly concerned with the type of investigation that can be carried out in the megacycle range of frequencies from a few megacycles to kilomegacycles; it deals almost entirely with short-duration pulse methods rather than with standing-wave methods. The book opens with a chapter on a classical treatment of wave propagation in solids. This is followed by separate chapters on methods and techniques of ultrasonic pulse echo measurements, and the physics of ultrasonically measurable properties of solids. It is hoped that this book will provide the reader with the special background necessary to read critically the many research papers and special articles concerned with the use of ultrasonic methods in solid state physics. The book is intended to help the person beginning work in this field. At the same time, it will also be useful to those actively involved in such work. An attempt has been made to provide a fairly general and unified treatment suitable for graduate students and others without extensive experience.

Download or read book Harmonic Generation of Microwave Phonons written by Paul Henry Carr and published by . This book was released on 1969 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to produce coherent phonons of microwave frequency provides a much needed means of investigating fundamental phenomena in solid state physics at frequencies never before attained. It is shown for the first time that second and third harmonics of the fundamental acoustic wave are also generated. The fact that the secondharmonic acoustic power was observed to be proportional to the square of the fundamental and the third-harmonic acoustic power proportional to the cube of the fundamental establishes the nonlinearity of the generation mechanism. Second-harmonic generation of longitudinal phonons in nonpiezoelectric Z-cut quartz was observed. The generation mechanism is common to all dielectric media. This demonstrates that coherent phonon generation is not restricted to relatively rare piezoelectric materials. The highest frequency at which microwave phonons can be generated is limited to 80 Gcps by present-day highpower microwave sources. The successful generation of harmonics of microwave phonons enhances the possibility of extending the present limit well into the millimeter range. Fundamental research of this type can lead to such practical control devices as microwave delay lines since the acoustic delay time of one centimeter of quartz is the same as that of 500 meters of waveguide.
