Interaction of a point charge with the surface of a uniaxial dielectric

Primoz Rebernik Ribic

We analyze the force on a point charge moving at relativistic speeds parallel to the surface of a uniaxial dielectric. Two cases are examined: a lossless dielectric with no dispersion and a dielectric with a plasma-type response. The treatment focuses on t ...

Switchable Selective Absorber Coatings for Overheating Protection of Solar Thermal Collectors

Antonio Paone

Overheating is a common problem both with the use of active and passive solar energy in solar thermal energy systems and in highly glazed buildings. In solar thermal collectors, the elevated temperatures occurring during stagnation result in reduced lifeti ...

Laser-Heating-Induced Displacement of Surfactants on the Water Surface

Sylvie Roke

We report a combined vibrational sum-frequency generation (SFG) spectroscopy, Brewster angle microscopy (BAM), and ellipsometry study of different surfactants on water as a function of surfactant density. Vibrational SFG spectra of surfactants on the water ...

Electrical and optical properties of Ta-Si-N thin films deposited by reactive magnetron sputtering

Rosendo Sanjines, David Oezer

The electrical and optical properties of TaxSiyNz thin films deposited by reactive magnetron sputtering from individual Ta and Si targets were studied in order to investigate the effects of nitrogen and silicon contents on both properties and their correla ...

Oblique incidence design of meander-line polarizers for dielectric lens antennas

Juan Ramon Mosig, Jean-François Zürcher, Benjamin Fuchs, Benjamin Fuchs, Marco Letizia

A method to design planar multilayer meander-line polarizers is given. The proposed procedure is based on transmission line circuit theory and on full-wave unit cell analysis in frequency domain. The hybrid combination of those two techniques paves the way ...

Study of wave attenuation across parallel fractures using propagator matrix method

Jian Zhao, Jianbo Zhu

Stress wave attenuation across fractured rock masses is a great concern of underground structure safety. This paper presents an analytical study on wave attenuation across parallel fractures at arbitrary incidence angles, where multiple reflections occurri ...

Atomic-scale engineering of magnetic anisotropy of nanostructures through interfaces and interlines

Harald Brune, Stefano Rusponi, Philipp Buluschek, Sergio Vlaic

The central goals of nanoscale magnetic materials science are the self-assembly of the smallest structure exhibiting ferromagnetic hysteresis at room temperature, and the assembly of these structures into the highest density patterns. The focus has been on ...
