    The Effect of Gum Arabic on Extra Transmission from Polystyrene/Zn++ Hybrid Photonic Crystal
    (2017-01-02) Mohammed Ahmed, Mubarak; Mohammed Al-khair Dirar, Hatim
    Polystyrene (PS) photonic crystal doped with Zn++ prepared by foam reaction method had showed an extraordinary transmission peaks after adding Gum Arabic .such transmission enhancement can be attributed the strong plasmons-plaritons coupling. From other hand the enhancement

    Fabrication of Tunable Polystyrene Photonic Crystal Using Gum Arabic via Foam Reaction
    (كلية الدراسات العليا جامعة النيلين, 2016-06-01) Mohammed Ahmed, Mubarak; Mohammed Elkhair, Hatim
    Polystyrene(PS)/ZnO/Gum Arabic photonic crystals, prepared by foam reaction had exhibited tunable photonic band gap as being detected by optical transmission experiments with slight shift as shown by the transmission spectra ,such tunability might be attributed to the effect formation caused by PS/ZnO volume fraction .
