Waves in anisotropic metamaterials comprised of finite L-C meshes
Bibliographic record
Abstract
2D periodic lattices and finite grids of lumped L-C elements have been investigated to elucidate the mechanisms governing wave phenomena in this kind of metamaterial. Isofrequencies for a lattice unit cell and circuit simulations of finite meshes have shown that such a medium exhibits unusual properties of channeling power from a point source into pencil beams which can propagate only along specific trajectories. The beam direction varies with frequency, and at the resonance frequency /spl omega/ = 1/(LC)/sup 1/2 /, the phase and group velocities of the transmitted wave are orthogonal. It is shown that the channeled beams do not obey the laws of geometrical optics (Snell's law, Brewster angle, etc.) at the skewed interfaces of dissimilar meshes, and that beam scattering is governed by the local conditions of the phase synchronization and impedance matching. Finally a new physical planar L-C mesh unit cell arrangement has been designed and measured.

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.
