Abstract
A customized integrated circuit (IC) is presented that is designed specifically for implementing complex-impedance metasurface loading elements. This IC enables innovative metasurface designs that target absorption applications. Through targeted electronic and electromagnetic co-design, we propose an innovative metasurface unit cell to implement a tunable metasurface absorber. We demonstrate the proposed loading element performance range through a fabricated custom IC. Experimental measurements of the fabricated loading element circuit in a 180 nm CMOS technology are used in an electromagnetic simulator to demonstrate tunable perfect absorption at normal and oblique angles of incidence for both transverse electric (TE) and transverse magnetic (TM) polarizations. With four of the proposed loading elements, realized on a custom IC, the metasurface absorber is shown to control independently and simultaneously the absorption of both TE and TM polarizations.

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
