Abstract

fetched live from OpenAlex

In this paper, a method for obtaining the generalized scattering matrix coefficients of both the propagating and evanescent modes of waveguide discontinuities is presented. The method is based on the modal expansion of field distributions obtained from Transmission Line Matrix (TLM) simulations and use of the orthogonality principle to quantify the presence of specific modes. Using this approach, the coefficients have been evaluated close to discontinuities in the presence of higher order propagating as well as evanescent modes. This simple and rigorous approach enables us to characterize a discontinuity with reduced computational effort.

Full frame distilled prediction

Teacher imitation

Not 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.
