Abstract
The authors focus on the indoor site-specific modeling of radiowave propagation. In indoor environments, home or office buildings, most of the structures causing diffraction can be categorized into half planes, such as soft and hard partitions, and right-angle wedges, such its wall corners. They study the total field, including incident, reflected, diffracted and/or transmitted fields, in the whole space around the right-angle wedge and thick lossy dielectric half plane for both TE and TM polarisations. Transmission and reflection coefficients are given for lossy dielectric slabs, which are included in the modified UTD formula. Results are compared to those obtained by the FDTD method so as to evaluate the UTD based methods.

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 it
