Abstract
<p> The time reversal method has been shown to be capable of reconstructing electromagnetic sources. However, in the past, most sources reconstructed are point sources that may not be often seen in practical situations. This paper presents preliminary studies on the time-reversal reconstruction of the sources with arbitrary geometrical shapes and with finite frequency bandwidths. Our results show that the time-reversal method, incorporating the Kurtosis, can effectively find the locations, excitation, and band-limited arbitrarily shaped sources. In addition, in an ergodic cavity, a single sensor is adequate to reconstruct the sources with reduced operational cost and complexity.This paper lays the groundwork for further development of the TR method for its uses in realistic scenarios of source reconstructions. </p>

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
