Fine zinc oxide particles were electrophoretically deposited  on alumino-ferro-chrome substrates. The deposition was carried out in a cylindrical ZnO/acetone electrophoresis cell. The deposits were dried and sintered at 1030³C in air. The process resulted a porous polycrystalline ZnO cladding over the alloy core. Comb shaped silver electrodes were formed and fired at 350³C. The variation of dev...

Based on vector diffraction theory and annular Walsh function filter, axially splitted ultra-long multiple optical needles/optical tubes of electric as well magnetic field distributions are numerically generated by generalized cylindrical Bessel Gaussian beam phase modulated filter. This structures can be conveniently tailored properly tuning the initial Cylindrical (CVB) order Furthermore, eff...
