A numerical method is used to describe the angular amplitude and phase responses of non-saturation limited parametric arrays especially within the interaction region of the arrays. Far"eld expression of the primary waves are employed in the method to approximate the primary "elds. It is shown that t

β¦ Synopsis
A theoretical treatment is formulated for the angular dependence of an absorption-limited parametric array. This allows analytical results for the off-axis far field amplitude and phase responses to be readily obtained. Experimental results show good agreement with the theory.

An analytical solution is developed for the problem of transient diffusion and first order reaction in a solid flanked by two well mixed fluid compartments. This solution is necessary and useful in describing unsteady-state measurements in a Wicke-Kallenbach diffusion cell or reaction studies in a s
