The effect of parametric wave phase conjugation (WPC) in application to ultrasound acoustic waves in magne-tostrictive solids has been addressed numerically in [1] using 1-D unsteady formulation. Here we apply the numerical method presented in [2], [3] to the analysis of probable 2-D effects by practical implementation of WPC, The model describes universally elastic solids and liquids. A source term is included in the model similar to [1] to describe coupling between deformation of magnetostrictive material and external periodic magnetic field. Supplementary to the 1-D simulations, the present model involves longitudinal/transversal mode conversion at the sample boundaries and separate magnetic field coupling with dilatation and shear stress. The influence of those factors in a 2-D geometry on the potential output of a magneto-elastic wave phase conjugator is analyzed in this paper. The process under study includes propagation of a wave burst of a given frequency from a point source in a liquid into the active solid, amplification of the waves due to parametric resonance and formation of time-reversed waves, their radiation into liquid and focusing.
