A theoretical means of obtaining the pressure field between two infinite elastic plates one of which is excited by periodic pulses applied at a point is developed. The Timoshenko-Mindlin plate equation, which includes the effects of rotatory inertia and shear deformation, is used to describe the motion of each of the plates. The fluid between the plates is assumed to be compressible and inviscid and is described by the fluid wave equation. The solution is obtained by use of Hankel transforms. The inverse Hankel transform is obtained by numerical integration and by an approximation using the method of steepest descent. Satisfactory agreement between the two sets of results were found for pulse lengths on the order of ten microseconds. Author
