Fractured vuggy reservoirs exhibit intricate fracture networks, where large fractures impose significant shielding effects on smaller ones, posing formidable challenges for efficient exploitation. A systematic evaluation of foaming volume, drainage half-life, decay behavior, and viscosity under varying temperatures and salinities was conducted …

A dual-control reconfigurable intelligent metasurface (DC-RIMS) composed of$24\times 22$symmetric cells in the 5G mid-band is proposed. The DC-RIMS of non-artificial-magnetic-conductor type provides a smaller phase resolution of$60^{\mathrm{o}}$with 2 bits under normal incidence. Angular sensitivities of the RIMS under oblique incidence are investigated. …
