Abstract
The Cagniard-de Hoop method is applied to Lamb’s problem of the impulsive line and point source on an elastic half space leading to analytical expressions for the longitudinal and transverse wave components throughout the half-space without any approximation. For realistic transducer excitation broadband radiation patterns are obtained by convolution and compared to the time harmonic far-field patterns of Miller-Pursey and Roderick; they include the headwave influence and indicate a near- to far-field behavior even for idealized point- and line sources.
