Abstract
Forward electromagnetic (EM) solutions must be sufficiently accurate in order to be used in the solution of the inverse problem of microwave medical imaging. Two well-known issues related to the adequacy of the forward EM solutions are: 1) the feasibility of 2-D approximations and 2) the effect of the skin interface. In this paper, we present a systematic study using the time-domain EM solver XFDTD to assess the applicability of related approximations. This preliminary investigation leads us to believe that a 2-D simulation is not an adequate representation of the forward problem and may be misleading when testing inverse solvers. Also, the skin interface must be modeled correctly regardless of how well the properties of the coupling medium match those of the breast tissue. Ultra-wide band responses are studied and numerous plots are presented to support our conclusions.

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
