Abstract
This work conceptualizes wireless power transfer (WPT) between a tracking stationary ground transmitter and a mobile aircraft. Initial ground tests are performed to determine the viability of the Friis equation, using rectennas developed for operation at 2.45 GHz at 4 dBm of optimal input power. An achieved rectifier operation efficiency of 59% is reached at this power level. A model for analyzing received power during WPT tests in flight conditions is then developed and applied for various flight paths possible with a small, electric UAV, using the designed rectenna for power conversion on the aircraft. A maximum of 429 mW is received when the aircraft is flown in a circular path centered around the ground transmitter, with a radiated power of 7 kW. Various other loiters are also analyzed, including racetrack, elliptical, and infinity‐shaped loiters. The racetrack and elliptical loiters performed similarly with an approximate transmitted power of 4.5 kW and received power of 300 mW. The infinity loiter performed the worst with only 150 mW of received power with nearly 8.2 kW transmitted, which occurred primarily due to polarization mismatch between the transmitter and rectenna.

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
