We investigate the generation of magnetic fields above black hole accretion disks due to the nonzero curl of the disk radiation field. By self-consistently computing the components of the radiation flux and their curl, we show that the rotational nature of the radiation field induces charge separati...

An optical phase shifter based on narrow-core hollow waveguide is proposed. The light is guided in an air core between the top and bottom reflectors made up of silicon and indium tin oxide (ITO) gratings. The proposed narrow-core hollow structure is able to guide slow light mode with a low loss of 0...
