Abstract
An ultra-wideband dielectric-filled antenna has been designed for the purpose of breast cancer detection. The antenna geometry is a modified version of a slotline bowtie hybrid, which is immersed in a dielectric medium, and fed with an integrated ultra-wideband balun. Simulations were performed on both the balun and the antenna separately. The antenna had a simulated time domain near-field beamwidth of 32°. A return loss of 10 dB was obtained from 2.5 to 9 GHz, and 5 dB from 1 to 10 GHz. Both bandwidths were slightly smaller than simulated. A prototype was constructed and feasibility tests were performed on tumour models immersed in a breast phantom material. Measurements demonstrate detection of a 7 mm diameter tumour at a depth of 4 cm from the aperture.

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
