Using the transport of ions in matter program which is TRIM that based on a Monte Carlo simulation method to calculate sputtering yield for polypropylene, was bombed with (N2, O2, and Ar) gas energy range (0.1-300) Kev different angles. It can be seen from results this study depends incident angle, energy, atomic number ions, surface binding elements make up polypropylene (pp) polypropylene. no...

Radiation characteristics of fused quartz containing bubbles (10 % porosity) are determined using inverse method based on theoretical and experimental bi-directional transmittances and reflectances. The Discrete Ordinates Method is used to solve the RTE. The internal and external interfaces are assumed to be optically smooth. The importance of the choice of the interpolation law has been shown,...

Dynamical scattering effects are observed in grazing-incidence X-ray diffraction experiments using an organic thin film of 2,2':6',2''-ternaphthalene grown on oxidized silicon as substrate. Here, a splitting of all Bragg peaks in the out-of-plane direction (z-direction) has been observed, the magnitude of which depends both on the incidence angle of the primary beam and the out-of-plane angle o...

When a ball is incident obliquely on a flat surface, the rebound spin, speed, and angle generally differ from the corresponding incident values. Measurements of all three quantities were made using a digital video camera to film the bounce of a tennis ball incident with zero spin at various angles on several different surfaces. The maximum spin rate of a spherical ball is determined by the cond...

Extraordinary optical transmission through rectangular Sierpinski -Carpet aperture array on an Ag film has been observed. Attributed to the fractal-featured rectangle array, it exhibits polarization dependence and dual-band transmission simultaneously. In addition, the incident angle invariance transmission displays within a certain angle range, which is quite different from ordinary rectangles...

We investigate experimentally far-field scattering from cylinders with illumination non-uniform along the axis of the cylinder. Scattered intensity as a function of angle in two orthogonal directions is examined. Variation along the scattering angle is found to be little affected by the illumination profile. However, variation in the transverse direction follows closely the Fourier transform of...

The presence of a probe molecule is not required in Brewster angle microscopy (BAt\1) [5,6J. This technique is based on the fact that p-polarized light is not reflected at an interface when incident under the Brewster angle, which is about 53" for the air/water interface when using Address Max-Planck-Institut fUr biophysikalische Chemie, Postfach 2841, D-37018 Gottinqen, Germany; e-mail: dmoebi...

An exact analytical solution is obtained for the scattering of electromagnetic waves from a plane wave with arbitrary directions of propagation and polarization by an aggregate of interacting homogeneous uniaxial anisotropic spheres with parallel primary optical axes. The expansion coefficients of a plane wave with arbitrary directions of propagation and polarization, for both TM and TE modes, ...
