An electromagnetic wave attenuation superposition structure for thin-layer plasma

This work proposes a new plasma super-phase gradient metasurfaces (PS-PGMs) structure, owing to the limitations of the thin-layer plasma for electromagnetic wave attenuation. Based on the cross-shaped surface unit configuration, we have designed the X-band absorbing structure through the dispersion control method. By setting up the Drude dispersion model in the computer simulation technology, the designed phase gradient metasurfaces structure is superposed over the plasma, and the PS-PGMs structure is constructed. The electromagnetic scattering characteristics of the new structure have been simulated, and the reflectance measurement has been carried out to verify the absorbing effect. The results demonstrate that the attenuation effect of the new structure is superior to that of the pure plasma structure, which invokes an improved attenuation effect from the thin layer plasma, thus enhancing the feasibility of applying the plasma stealth technology to the local stealth of the strong scattering part of a combat aircraft.     

1000 kV苏通GIL管廊检修监理管控要点

1000 kV苏通GIL管廊工程是华东地区特高压交流环网合环运行的"咽喉要道"和控制性工程.该工程于2019年9月投运,并于2020年开展停电首检工作.为了严格贯彻"应修必修、修必修好"的原则,确保本次停电检修的质量,监理单位需在检修过程中对检修情况进行严格的控制.通过对实践经验的总结,分别从检修准备阶段、检修阶段和检修完验收阶段三个阶段着重阐述了苏通GIL管廊检修过程中监理管控的要点.
