  • Publication number: 20200353478
    Abstract: Systems and methods are disclosed for use in the separation of chiral compounds, and enantiomers in particular. The system comprises a cavity (110) for containing a fluid mixture that comprises one or more types of chiral molecules, which may also include enantiomers, and at least one ferromagnetic or paramagnetic substrate (120) providing at least one interface (130) with said fluid mixture. The substrate (120) is magnetized providing a magnetic field Bz perpendicular to said ferromagnetic or paramagnetic interface (130), thereby providing a variation in the interaction energy of chiral molecules of different handedness, aka. enantiomers, with said substrate (120).

  • Publication number: 20120248402
    Abstract: An emitter device for emitting electromagnetic radiation is presented. The device includes a metallic patterned structure, and emitting media integral with the metallic patterned structure. The emitting media includes one or more emitters of omni-directional emission in nature wherein certain emission pattern. One or more parameters of the metallic patterned structure, that define a dispersion map thereof, are selected according to the emitting pattern such that the metallic patterned structure operates as a beam shaper creating resonant coupling of each emitter with a microscopic confined optical mode of the metallic patterned structure thereby enhancing by a predetermined enhancement factor the emission from the emitting media in a predetermined direction. The device thus provides predetermined directional beaming of output electromagnetic radiation wherein a predetermined angular propagation of the electromagnetic radiation emitted by the emitting media.
