    Research and application of multi-beam antenna technology for home network based on SSPP technology by Shengbing SHI, Jinjin SHAO, Cao SHI

    Published 2023-09-01
    “…High-quality home wireless network with large bandwidth, wide coverage, low latency and anti-interference is the key indicator to ensure user experience of fiber to the room (FTTR) Gigabit optical network.Traditional home network equipment mainly adopts single-beam single-polarized antenna design, which has become increasingly unable to meet the needs of high-quality network products under the background of large attenuation and strong interference.Antenna, as an indispensable component to realize conduction energy and air-interface electromagnetic wave transformation, can realize multiple functions by using its design freedom.High gain can reduce the power consumption of the radio frequency (RF) side to achieve the purpose of energy saving, and multi-beam can maintain high-performance network coverage without dead ends.Therefore, designing a multi-beam antenna with small size, high gain and flexible usage is of great value.Following the practical engineering and current academic research, a multi-beam antenna based on spoof surface plasmon polariton (SSPP) technology, covering the 5.1~5.9 GHz frequency band of Wi-Fi, was designed for home network products.Compared with traditional antennas, the test results of the antenna based on SPSS technology show that the coverage performance of the network in weak signal scenarios such as through-wall and cross-layer scenarios is improved greatly.It has great application prospects in increasingly miniaturized home terminal products.…”

    Analytical Method for Fluid-Solid Coupling Vibration Analysis of Hydraulic Pipeline System with Hinged Ends by Tianxiao Zhang, Jin Cui

    Published 2021-01-01
    “…The vibrations in hydraulic pipeline systems inevitably involve the interaction between the two-phase media of a solid and fluid. The fluid flowing in the pipeline generates pressure on the pipeline wall and thus causes vibration and deformation in the pipeline, which in turn changes the fluid flow condition, thereby cyclically affecting the deformation and motion of the solid and fluid and making the pipeline system vulnerable to vibration damage. …”

    Experimental Study of Water and Sediment Separation under Hydrocyclone and Flocculation by FU Xuhui, SONG Yuanyuan, HU Jiang, TANG Dingdan, WANG Shuo, CAO Changlai

    Published 2020-01-01
    “…In order to study the effect of the combined technology of hydrocyclone and flocculation on the sediment content of water bodies,this paper measures the surface velocity and turbidity by a laboratory self-circulating physical model,ADV and ASM-IV turbidimeter,and analyzes the flow pattern and sediment distribution in the hydrocyclone pool.The results show that:The internal flow field of the hydrocyclone pool is a typical three-dimensional axisymmetric flow field;the turbidity in the hydrocyclone pool gradually decreases from the side wall to the center in the radial direction,and the turbidity gradually increases in the axial direction.Under the same sediment conditions,when the flocculant concentration was 5 mg/L,the effect of final sediment contents in purified water (water purified by the outer ring twice) is the best;the smaller the inlet flow of the hydrocyclone pool,the smaller the final sediment content in purified water.Compared with flocculant,inlet flow has a greater impact on the final sediment content in purified water,so it is a key factor in reducing the sediment content. …”
