The eikonal approximation is considered for propagation in an inhomogeneous, time-dependent, anisotropic environment. The usual eikonal analysis is generalized to take into account constitutive relations which contain space and time derivatives of the field quantities. The field equations are obtained for ...

Backscattering of Electrons Evaluated by the Eikonal-approximationAlmost all experimental values of backscattering rates of fast electrons (2060 keV) by thin foils are larger by a factor of 1.5 to 3 than theoretical values, based on Born''s first approximation. Using the eikonal series ansatz an ...
The equation determining S, termed the eikonal equation, constitutes a central result of the eikonal approximation, and one obtains it by using Eq. (2.3) in Eqs. (2.2a) and (2.2b), while retaining terms in the leading order of 1k0 in the resulting formulae: (2.4a)gradS2=n2, or ...
In a classical scattering problem, the classical eikonal is defined as the generator of the canonical transformation that maps in-states to out-states. It can be regarded as the classical limit of the log of the quantum S-matrix. In a classical analog of the Born approximation in quantum mec...
An eikonal approximation for nonlinear equations is derived from an expansion in powers of space and time derivatives. For the special case of one dependent variable, the method is equivalent to an averaging method proposed by Whitham and derived by Luke. A general solution for each order of the...
