A 2D (axisymmetric) computational study of the discharge characteristics of an atmospheric pressure plasma jet as a function of gas flow rate was performed. The helium jet emerged from a dielectric tube, with an average gas flow velocity in the range 2.5–20 m s−1 (1 atm, 300 K) in a nitrogen ambient, and impinged on a substrate a short distance dowstream. The effect of the substrate conductivit...

The authors realize a 50% length reduction of short-slot couplers in a post-wall dielectric substrate by two techniques. One is to introduce hollow rectangular holes near the side walls of the coupled region. The difference of phase constant between the TE10 and TE20 propagating modes increases and the required length to realize a desired dividing ratio is reduced. Another is to remove two refl...

Abstract Recently, aluminium alloys are extensively used in the construction sector because of their small self-weight, good corrosion resistance, low maintenance, high recyclability, and aesthetic appearance. However, one main disadvantages these is Young’s modulus, which may cause a stability issue structural members. Moreover, currently available design standards for predicting buckling resi...

• Capillary tubes & SAW devices used to pattern particles in no-flow flowing setups Rectangular tube: particle lines are parallel tube sidewalls for all directions Circular alignment depends on their position along the height Bottom/mid height: parallel/perpendicular direction Continues flow: always flow Acoustofluidic platforms have great potentials integrate capillary controlling and manipula...
