- Abdel-Aleam Mohamed (Taibah University)
An isotropic dielectric photonic crystal has been designed and demonstrated at the University of Illinois. The entire multidimensional structure is fabricated in a flexible polymer and the lattice constant is currently 500 μm. Interspersing 355 μm diameter microchannels along three spatial coordinates allows the plasma filling factor to increase to ~ 10%. The ignition of plasma within...
Atmospheric-pressure argon cold plasma jet was used to study the effect of applied voltage on the laminar to turbulent transition. The plasma jet consists of a quartz tube of inner and outer diameters of 2 mm and 6 mm, respectively. Two identical copper-sheets of 7 mm width are warped around the quartz tube. The sheets are separated by 35 mm and the upper sheet is connected to an AC...
Decomposition of 2,4-dichlorobenzonic acid (DCBA) in hydroponic nutrient solution using discharge inside bubble is investigated. Air gas is injected into water through a vertically positioned glass tube, into which high voltage wire electrode is placed to generate plasmas at low applied voltage. A magnetic pulse compression circuit is used to generate high voltage pulses. The concentration of...
The development of corona-like discharges that are instigated in water by the application of high voltage pulses is not only important for switching applications but also for discharges that are exploited for water treatment [1]. A parameter that is affecting discharge developments and foremost inception voltages is the pulse shape (rise time, amplitude, pulse duration) but in particular water...
Atmospheric pressure plasma jets have been widely used for biomedical applications. However, characteristics of discharge could vary dramatically depending on the biological substrates which further affects the treatment results. In this study, effects of three substrates (i.e. water, saline and pig skin) on electrical and optical properties of a pulsed helium plasma jet powered by 200 ns, 7...
Future wireless communications systems are driving system operating frequencies to the 100 - 500 GHz region. The stringent demands of 5G and 5G+ systems are accelerating the development of new sources and devices, such as resonators and filters. We report here the realization of dynamic filters through multidimensional microplasma photonic crystals. These crystals comprise spatially-periodic...
