Evolution of the PDMS-Housed Near-Field Sensing Array for Microwave Breast Screening
Bibliographic record
Abstract
Microwave breast cancer screening relies on the performance and robustness of the sensing element, which directly impacts detection accuracy and reliability. This paper presents a flexible cavity-backed hybrid patch/slot nearfield antenna embedded in polydimethylsiloxane (PDMS), a biocompatible polymer designed for integration with wearable or conformal medical imaging systems. Two successive design iterations were evaluated through full-wave electromagnetic simulations, focusing on impedance matching, mutual coupling, and specific absorption rate (SAR) compliance to ensure safe and effective operation. Simulations were conducted for both designs, and experimental measurements were performed on the initial prototype in proximity to various biological tissues to validate its practical feasibility. The results highlight the importance of the steps in the evolution of the sensing-element design and its potential for enhanced sensitivity and increased compatibility with microwave breast screening applications.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
