Abstract
Wireless power transfer (WPT) using magnetic coupling between loop antennas is an emerging technology, which could solve difficulties and hazardous technical problems of wired power transmission. From several millimeters to several hundred millimeters, WPT technology has reached kilowatts power level with high grid load of efficiency, which has brought significant benefits to medical applications, automation systems, consumer electronics, etc. Yet, WPT systems are extremely sensitive to the alignment between the transmitting and the receiving coils. A dual transmitter topology has been proposed to overcome the misalignment problems and maintain high power transfer efficiency. Nevertheless, the misalignment sensitivity between the transmitters was not considered. A comparative study based on the Theory of Characteristic Modes between three different topologies of the transmitting systems in MHz level is conducted in this paper. To enhance the comparison, the power transfer efficiencies of the three models are calculated regarding the same positions of the receiver.

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
