المستخلص: 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 might be due to the formation of PS/ZnO hybrid photonic crystal as being depicted from the nearest band edge absorption around 300nm. Hybrid photonic Plasmonic crystals characterized by strong coupling between photonic and Plasmonic crystals excitations, dielectric photonic crystal is used as template for deposition of metal films, the hybridization operation which is depend on the chemical reaction that is used .In this work foam reaction is used as to fabricate photonic crystal. Hybrid process might increased or reduced the transmission, by increasing or reducing reflections, because of the corrugated and formed thin film metal that make coupling with surface plasmons plaritons modes through a thin film ,results of bands of increasing transmission and the reflection reduced ,which causes an extraordinary transmission peaks which were shown in this study .the increasing of the transmission is due to the corrugated layers which is caused by Zn metal under the polystyrene particles ,these layers make total internal reflection leads to the increasing of the transmission, and this reduced reflection on the polystyrene particles which is self-assembled.
