Abstract: We have proposed and simulated optical schemes for producing reduced images by X-ray lasers or harmonic generators at a wavelength of . The mask in this case is placed at a small angle to the optical axis, corresponding to the angle of total external reflection of the material. We have determined the optimal position of the detector (resist) and the corresponding spatial resolution. The results can be used to solve problems in nanotechnology and nanostructuring of surfaces.

TL;DR: In this paper, an extension of the exact X-ray resonant magnetic reflectivity theory has been developed, taking into account the small value of the magnetic terms in the Xray susceptibility tensor.
Abstract: An extension of the exact X-ray resonant magnetic reflectivity theory has been developed, taking into account the small value of the magnetic terms in the X-ray susceptibility tensor. It is shown that squared standing waves (fourth power of the total electric field) determine the output of the magnetic addition to the total reflectivity from a magnetic multilayer. The obtained generalized kinematical approach essentially speeds up the calculation of the asymmetry ratio in the magnetic reflectivity. The developed approach easily explains the peculiarities of the angular dependence of the reflectivity with the rotated polarization (such as the peak at the critical angle of the total external reflection). The revealed dependence of the magnetic part of the total reflectivity on the squared standing waves means that the selection of the reflectivity with the rotated polarization ensures higher sensitivity to the depth profiles of magnetization than the secondary radiation at the specular reflection condition.

TL;DR: In this paper, the influence of implantation defects on Bragg diffracted and on diffuse intensities was investigated and the authors detected the presence of amorphous layers and determined their thickness.
Abstract: X-rays incident on a surface under grazing angle may undergo total external reflection and excite an interior wave field damped exponentially into the bulk. These evanescent waves are a sensitive probe for the study the real structure in the near surface region. We report results on the influence of implantation defects on Bragg diffracted and on diffuse intensities. By detailed comparison of Bragg intensities with predictions of dynamical scattering theory we detect the presence of amorphous layers and determine their thickness. For the first time defect induced diffuse scattering underconditions of grazing incidence andexit is observed and compared to recent theoretical results. Strength and symmetry of implantation induced defects can be determined as well as their depth distribution which is compared to results of a TRIM simulation: the defect distribution is found to agree with that of the deposited collisional energy.

TL;DR: In this paper, the experimental spectra of the optical reflection and transmission in a composite layer (PMMA+Ag) with silver nanoparticles is described. And the formulae for the reflectivity and transparency of a layer with a quasi-zero refractive index are recovered by considering its unique optical properties.

TL;DR: In this article, the reflection and refraction of plane magnetohydrodynamic waves at an interface separating two different media is studied for various orientations of the external magnetic field, and it is pointed out that by making use of trace velocity plots it is a simple matter to determine the nature and disposition of the reflected and refracted waves which are generated by an incident wave of any given species.
