| Abstract: |
Linear and nonlinear acousto-electric waves in porous solids in the presence of an electric field are investigated. The pores are filled with an electro-conductive liquid. The resulting self-consistent problem is solved while all the factors accompanying the wave being taken into account. Formulae for the wave’s linear and nonlinear speeds and absorbtion coefficients are derived. Both 1-dimensional and 3-dimensional cases have been considered. Nonlinear evolutionary and Schrodinger equations are derived. Their solutions are obtained and investigated in detail. It is shown that there can be soliton-shaped waves in the medium. |
