Focusing Ultrasonic Field of Holed Cap Spherical Shell Transducer Using the Spheroidal Beam Equation
-
Abstract
A large aperture transducer with an inner hole has been used to validate the feasibility of using the spheroidal beam equation to solve the acoustic field of the inner holed transducer. The numerical results several harmonics are presented for the nonlinear field.
