摘要: A theoretical model of focused acoustic field for a multi-annular phased array on concave spherical surface is proposed. In this model, the source boundary conditions spheroidal beam equation (SBE) elements are studied. Acoustic calculated by dynamic focusing SBE compared with numerical results O'Neil and Khokhlov—Zabolotskaya—Kuznetsov (KZK) respectively. Axial harmonic effects presented. The demonstrate that good valid large aperture angle in linear or nonlinear field.
