   Abstract Molecular clusters can function as nanoscale atoms/superatoms, assembling into superatomic solids, a new class of solid‐state materials with designable properties through modifications on superatoms. To explore possibilities on diversifying building blocks, here we thoroughly studied one representative superatom, Co₆Se₈(PEt₃)₆. We probed its structural, electronic, and magnetic properties and revealed its detailed electronic structure as valence electrons delocalize over inorganic [Co₆Se₈] core while ligands function as an insulated shell.⁵⁹Co SSNMR measurements on the core and³¹P,¹³C on the ligands show that the neutral Co₆Se₈(PEt₃)₆is diamagnetic and symmetric, with all ligands magnetically equivalent. Quantum computations cross‐validate NMR results and reveal degenerate delocalized HOMO orbitals, indicating aromaticity. Ligand substitution keeps the inorganic core nearly intact. After losing one electron, the unpaired electron in [Co₆Se₈(PEt₃)₆]⁺¹is delocalized, causing paramagnetism and a delocalized electron spin. Notably, this feature of electron/spin delocalization over a large cluster is attractive for special single‐electron devices.

   In this paper, a 1-bit wideband reconfigurable intelligent surface (RIS) design operating at sub-6 band is proposed. The unit cells of the RIS surface are designed based on a three-layer stacked patch structure. Employing a 1-bit PIN diode to reconfigure the phase states, a phase difference of 𝟏𝟖𝟎𝟎 ± 𝟐𝟎𝟎 is observed over the frequency range of 4.81 – 5.77 GHz, corresponding to a 19.2% fractional bandwidth. The reflection magnitude of the unit cell is above –3 dB in the band of interest, and the cross-polarization of the scattered waves is found significantly lower than the single-patch structure. The RIS array with a dimension of 𝟖. 𝟐𝝀 × 𝟓. 𝟏𝝀 , corresponding to a 𝟏𝟔 × 𝟏𝟎 array is structured according to the proposed unit cell with good beam steering capabilities.
