Parametric Acoustic Array Formation Via Weak Collinear and Noncollinear INteraction in Diepersive Fluids.
Abstract
The effect of dispersion on parametric arrays formed by Gaussian beams is investigated via solutions of the nonlinear paraxial wave equation. Analytical solutions are obtained by employing the quasilinear approximation; the results are thus restricted to weakly nonlinear interactions. Both (i) collinear and (ii) noncollinear interactions of the primary beams are considered. (i) Axial field curves and farfield directivity patterns are presented for the difference-frequency signal resulting from collinear interaction of Gaussian beams.
