Representation of Linear Waves in Inhomogeneous Media
Abstract
The article explores the acoustic equations in inhomogeneous media and the linearized shallow water equations. Two methods for integrating these equations are proposed. The first method is based on the of the Laplace cascade method, while the second involves reducing two-dimensional and three-dimensional models to the wave equation. In the case of plane waves, solutions to some equations depending on two arbitrary functions are obtained. In the two-dimensional and three-dimensional cases, equations that can be reduced to equations with constant coefficients are found.
