Abstract
THIS is a remarkable tour de force. In five brief but lucid chapters on piezo-electric phenomena, piezo-electric crystals in high-frequency fields, the application of oscillating crystals in high-frequency technique and electro-acoustics, the applications in ultra-sonic technique and the significance of ultrasound in science and technics, the author presents a simple and amazingly complete picture of the applications of oscillating crystals. The book has a wealth of illustrations (more than one per page of text), of which neither half-tones nor line diagrams suffer any loss in value from the smallness of size which is imposed by the attractively compact form of this popular monograph.
