Part I of this paper first describes a method of measuring attenuation and field strength in the ultra-short-wave range. A resume of some of the quantitative experiments carried out in the range between 17 megacycles (17 meters) and 80 megacycles (3.75 meters) and with distances up to 100 kilometers is then given.

Wave phenomena are used to evaluate material properties nondestructively as well as to locate and measure defects in critical structures. In fact, physical acoustics is directly related to ultrasound since the ultrasonic waves are employed to determine the properties of materials.
