Abstract
The radiation patterns of an elastic wave field generated by circular plane compressional
and shear transducers are derived using the method of steepest descent. These patterns
contain both effects of the elastic half space and the amplitude modulation due to the
finite dimension of the piston source. Behaviors of radiation patterns of the generated
compressional and shear waves are shown for low, medium, and high frequencies. Laboratory
experiments have been performed to measure radiation patterns of compressional
and shear transducers. Theory and experiment are found to be in good agreement.
