On the sign of refraction in anisotropic non-magnetic media

The main message of this paper is that refraction of a narrow collimated beam at a negative angle into strongly anisotropic non-magnetic crystals—a phenomenon which was observed in a number of experiments—should not be confused with negative refraction and lacks important physical characteristics of the latter. In particular, it is shown that there is no contradiction between the theory previou...

Negative refraction in indefinite media

Initial experiments on wedge samples composed of isotropic metamaterials with simultaneously negative permittivity and permeability have indicated that electromagnetic radiation can be negatively refracted. In more recently reported experiments [Phys. Rev. Lett. 90, 1074011 (2003)], indefinite metamaterial samples, for which the permittivity and permeability tensors are negative along only cert...

Some experiments on independent component analysis of non-Gaussian processes

This paper reports on numerical experiments on the ‘independent component analysis’ (ICA) of some nonGaussian stochastic processes. It is found that the orthonormal basis discovered by ICA are strikingly close to wavelet basis.

Some problems with negative refraction.

Some Problems with Negative Refraction* by John Michael Williams P. O. Box 2697, Redwood City, CA 94064 [email protected] Abstract J. B. Pendry's "Negative Refraction Makes a Perfect Lens" is analyzed. It appears that several statements may be understood in terms of lens design but not in terms of fundamental behavior of light. In a recent Letter, "Negative Refraction Makes a Perfect Lens" (P...

Propagation of Love Waves in a Non-Homogeneous Elastic Media

The propagation of Love waves in a non-homogeneous layer of finite thickness lying over an isotropic semi-infinite medium is discussed in this study. It is assumed that density and rigidity are space dependent and obey the laws  (1+cosz), μ=μ0 (1+cosz), where ‘’is a scaling parameter. The method of variable separation, substitution method for solving the second order partial differen...
