A Comparison of Wearable Metasurfaces
Bibliographic record
Abstract
A metasurface was printed on two industrial fabrics using two commercially available inks, CM127-48 (Creative Materials), and PE876 (Dupont), via direct-write printing. The fabrics both had a polyurethane (PU) coating on the reverse side for mechanical reinforcement and for preventing ink from bleeding through to the other side. The woven nylon fabrics were distinguished by their thread mass (70D and 200 D). The metasurface was first designed for band stop at 6 GHz and characterized by radio frequency (RF) measurements and sheet resistance, Rs. All combinations of ink and substrate performed similarly and were consistent with simulations. By assessing initial performance and longevity, the best combination of materials was determined to be CM127-48 on EX. These materials were then used to fabricate a double-sided design, with a grid printed on the reverse side of the fabric, leading to a dual-band metasurface with rejection at 4.8 GHz and band pass at 2.6 GHz. This work presents, for the first time, an additive approach to fabricating novel fabric based dual-band filters using direct-write printing and addresses the challenges in controlling alignment when printing on both sides of a fabric substrate and printing on surfaces with different coatings.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
