2D transformation optics using anisotropic transmission-line metamaterials
Bibliographic record
Abstract
In this contribution we propose a two-dimensional metamaterial unit cell which synthesizes equivalent material parameters needed for `transformation optics', as introduced in. The proposed metamaterial consists of a grid of reactively loaded transmission-line segments and is a variation of the unit cell presented in, synthesizing also the required off-diagonal elements of the permeability tensor. The application of cloaking of the `transformation optics' approach is taken as a test case for the novel metamaterial. The cloak we present is different from the structure presented in in that it synthesizes not only μ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ρ</sub> and ∈ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">z</sub> but also μ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ø</sub> .

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.
