The Difference

The scattering properties of woven fibrous materials are examined in this paper and a simple model is presented to account for the interactions between the scattered radiation from different individual fibers. The case of a normally incident plane electromagnetic wave is considered. Fiber sizes in the Rayleigh regime are considered for developing closed-form solutions. Previous studies in the literature that have addressed the scattering properties of fibrous materials have mostly ignored the effect of constructive or destructive addition of scattered waves from individual fibers, the exception being the case of parallel fibers. The difference in the effects of interference on scattering properties of parallel fibers and of woven fabrics arises from the additional interaction of radiation scattered from mutually perpendicular fibers in the latter case, which further complicates the analysis.

The Face

A uniform, unbounded, cold plasma stream, with relativistic velocity (0,U, 0), traverses a vacuum half-spacey> 0 and a dielectric half-spacey< 0. A plane electromagnetic wave in the plasma stream iny> 0 is incident obliquely on the face of the dielectric. The criterion for determining which characteristic waves are present in each half space is discussed, and it is shown that, for the polarization in which B is parallel toy= 0, there is one reflected wave and three transmitted waves. One of the latter can be an amplifying wave. A first approximation to the transmission and reflexion coefficients is found in the case when the density of the stream is low.

Wave Incidence

A plane electromagnetic wave incident on the interface of a dielectric medium made of a piezoactive material leads to the excitation of elastic shear waves. Piezoelectric material is assumed to have 6mm class hexagonal symmetry. The case of a half-space and a finite layer is considered. Coefficients of reflection and refraction are determined. In the problem of an electromagnetic wave incidence on a half-space made of a piezoelectric material of hexagonal symmetry, class 6 mm, the nature of the piezoelectric effect influence on the transparency condition is established. In the case of reflection from a finite piezolayer, reflection coefficients are determined for different variants of boundary conditions.
