Arbitrary Electromagnetic Conductor Boundaries Using Faraday Rotation in a Grounded Ferrite Slab
Bibliographic record
Abstract
The realization of arbitrary perfect electromagnetic conductor boundaries by a grounded ferrite slab using Faraday rotation is proposed. This is the first practical realization of a perfect electromagnetic conductor boundary to the authors' knowledge. The key principle of the grounded ferrite perfect electromagnetic conductor boundary is the combination of Faraday rotation and reflection from the perfect electric conductor of the ground plane. From this combined effect, arbitrary angles between the incident and reflected fields can be obtained at the surface of the slab, so as to achieve arbitrary perfect electromagnetic conductor conditions by superposition with the incident field. An exact electromagnetic analysis of the structure is performed based on the generalized scattering matrix method and an in-depth description of its operation phenomenology is provided. As an illustration, a tunable transverse electromagnetic (TEM) waveguide with grounded ferrite PMC lateral walls is demonstrated experimentally. Due to its flexibility in the control of the polarization of the reflected field, the proposed grounded ferrite perfect electromagnetic conductor may find applications in various types of reflectors and polarization-based radio frequency identifiers.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
