Abstract
By means of modeling experiments on a wax slab, oil-coupled lithium sulfate transducers are found to have excellent directional properties as seismic modeling transducers. Investigation of the several orders of multiple reflection amplitudes shows that consistency in the measured reflection coefficients for the spherical wave fronts is easily achieved if a loss mechanism of the internal viscosity type is attributed to the wax.
