We have measured the high-angle x-ray diffraction from crystalline Pb-amorphous Ge multilayers. The experimental data in conjunction with a model calculation for the fluctuation in amorphous-layer thickness show that this fluctuation is larger than about 5%. A smaller thickness variation implies the existence of high-angle peaks which have not been observed in any amorphous-crystalline multilay...
today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. one of the almost endless and pure energy which have been paid attention over the years is the solar energy. solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. significant improvement has been made...
Wave diffraction is a very important phenomenon in marine engineering and several models have been developed for its simulation. The new version of SWAN, a third generation spectral model, includes an approximation to wave diffraction. The approximation is based on the mild-slope equation for refraction and diffraction, omitting phase information. The objective this paper is to evaluate the per...
We have proposed a new ultra-compact optical demultiplexer based on metal-insulator-metal plasmonic waveguides aperture-coupled to the ring resonators. Our proposed device has high performance, small footprint, and high potential for integration and development to more channels.
