Abstract
Abstract This paper presents an ultraminiaturized bandstop closed‐loop 2.5D frequency‐selective surface (FSS) for sub‐6 GHz 5G wireless communication. Four metallic vertical vias interconnect metallic elements present on both sides of the substrate to form a modified closed‐loop design. The proposed structure band stops the entire sub‐6 GHz 5G band (C‐band/NR N78 band/LTE 42/43 band) ranging from 3.2 to 3.9 GHz with a resonant notch at 3.62 GHz. This design supports polarization insensitivity and procures maximum relative deviation of 0.5% and 0.2% at 80°incident transverse electric (TE) and transverse magnetic (TM) polarized waves, respectively. The proposed FSS prototype has been fabricated and tested. Experimentally, the resonant notch is obtained at 3.55 and 3.68 GHz under TE and TM normal incident polarized waves, respectively. Moreover, good agreement in the frequency response curves is observed between simulated and measured results. The proposed unit cell is 3.6 × 3.6 mm 2 in dimensions, which is 0.04 λ × 0.04 λ , where λ is the resonant wavelength.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
