Physical Acoustics: Principles and Methods, Volume X, is a five-chapter text that covers the principles and methods of generation of physical acoustics. The first chapter provides the essential results obtained concerning acoustic surface waves on curved surfaces and relates them to the corresponding plane surface waves. This chapter also presents a classification of surface and lateral waves on flat surfaces along with their properties. The second chapter describes a group of acoustic wave problems that are particularly suitable for study by means of Schlieren visualization. The third chapter deals with the production of ultrasonic waves by direct electromagnetic generation, while type II superconductors, which are useful for superconducting magnets with strong magnetic fields and with high current densities, are investigated in the fourth chapter. The fifth chapter discusses the principles of hologram and its application to very short length electromagnetic waves known as microwaves and to acoustic waves of various wavelengths.
