In this paper the method for estimating the statistical parameters of the medium from traveltime measurements of refracted waves is applied to study the statistical characteristics of crystalline rocks at the Multifunctional Station Faido (Gotthard B

Analytical expression for the 2D Gaussian beam diffraction in a free space is derived from the eikonal-based form of complex geometrical optics (CGO). This expression has been proved in this paper to be identical both to the exact solution of parabol

The method for calculation of noise amplification in nonlinear systems near bifurcation point is suggested, which takes into account nonlinear saturation of fluctuations. The method is illustrated by two examples: saturation of noise amplification un

Influence of enhanced backscattering effect on laser measurements of dust and aerosols content in a turbulent atmosphere is discussed. It is shown that doubling of the backscattered light intensity, characteristic for enhanced backscattering leads to

Polarization methods used to sound ionospheric plasma are based on the Faraday and Cotton-Mouton effects. While the Faraday effect (rotation of the polarization plane) covers almost the entire ray path, the Cotton-Mouton effect gives rise to local tr

Caustics, Catastrophes and Wave Fields in a sense continues the treatment of the earlier volume 6'Geometrical Optics of Inhomogeneous Media'by analysing caustics and their fields on the basis of modern catastrophe theory. The present volume covers lo

The concept of longitudinal caustic scale l ‖ is introduced to consider limits of applicability of uniform Airy-asymptotics. The results are illustrated by two examples: a circular caustic and the caustic for cylindrical waves in a linear layer.

Backscattering enhancement is discussed as a universal wave phenomenon inherent to waves of whatever physical nature: electromagnetic, acoustic, spin, etc. This phenomenon arises due to multichannel wave propagation from a source to a scatterer and b
