Abstract

fetched live from OpenAlex

This paper presents a wearable wireless power transfer (WPT) system that utilizes fractal antennas integrated with a fractal metamaterial (MTM) layer. Simulations are carried out using ANSYS HFSS. The effects of changing the distance between transmitter and receiver antennas and the position of the MTM surface are studied in a layered model of human body tissues. Simulation results show improvement in multiband power transfer efficiency (PTE) with the use of an MTM surface. The self-similar structures in fractal metamaterial allow for a compact design and enhanced multiband performance. The effect of horizontal misalignment and lateral movements in the presence of MTM are reported.

Teacher imitation

Not 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.
