Abstract
Methods for calculation of the fields of parametric acoustic arrays operating in an inhomogeneous medium under regimes of low-frequency wave generation similar to the Westervelt and Berktay regimes for free space are discussed. Mode and ray representations of difference-frequency waves are used. Both plane isovelocity waveguides and refractive sound channels are investigated.
