Abstract

fetched live from OpenAlex

This paper presents the design of a mounting plate with a complex permittivity profile that minimizes the reflection from the mounting plate over a broad range of incidence angles while providing the mechanical rigidity necessary for mounting a styrofoam jig holding the device under test. The geometry is reminiscent of a honeycomb structure, and is modeled as a uniaxial medium with the optic axis parallel to the normal of the plate. A modified scattering matrix propagator scheme was developed to predict the reflection and the transmission coefficients for both the TE/sup z/ and TM/sup z/ polarizations in a way that takes into account explicitly both the non-uniform wave propagation resulting from the presence of material losses, and the longitudinal anisotropy resulting from the geometry of the machined plate. A choice of parameters that yields a predicted reflection level of less than -20 dB from 0/spl deg/ to 55/spl deg/ is presented.

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.
