Abstract

fetched live from OpenAlex

A new technique for accelerating the frequency sweep of MoM planar solvers is presented. It is referred to as the rapid frequency sweep (RFS) technique. The technique starts at the central frequency of the simulation band. At this frequency point, it calculates a number of basis integrals for each inner product term involved in the filling of the MoM impedance matrix. At each frequency point, a new set of weighting coefficients are evaluated. These coefficients are used to combine the basis integrals. The proposed RFS is applied to two microstrip circuits; namely, a lowpass filter and a branch line coupler. Results show that RFS offers high accuracy over a frequency band as wide as 150%. It is also very fast in comparison with the regular frequency sweep. For selected examples, a speed-up factor of about 12 is measured.

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.
