This generalization includes as special cases continuum-mechanical theories proposed by Mooney and by Rivlin and Saunders as improvements upon the classical neo-Hookean theory.

The wave conversion occurs through the phenomenon of electrokinetics, for which a complete set of partial differential equations was derived by S. Pride. In this paper, we show how Pride’s equations in plane layered media can be written in a convenient mathematical form suggested by B. Ursin, who used this form to give a unified the treatment of electromagnetic waves, acoustic waves and the waves of isotropic elasticity in plane layered media. We use Ursin’s formalism, which we develop and simplify for the case of a stack of homogeneous layers, to derive explicit formulas that can be made the basis of an efficient computer code. Numerical results are presented for spatially-extended electrode sources that have been used in field tests of ES prospecting. More generally, the methods developed are applicable to any system that can be put into Ursin’s form. In particular, the code that was written for ES can be modified to compute purely seismic waves, purely electromagnetic waves, or the waves of Biot theory, since all these phenomena are included in the equations of electrokinentics when parameters are specialized appropriately.
