Fields of a cell phone with a hands-free kit adapter
Bibliographic record
Abstract
This paper examines the electric field inside a simple model of the human head, due to a cellular telephone with a “hands-free kit” (HFK) adapter. The cell phone is a metal box with a quarter-wave monopole on the top. The HFK wire is connected to the bottom of the handset and runs up parallel to the body to a point near the location of the ear. The body, neck and head are represented with box models, including layers for the skin, muscle, and bone in the head, which is filled with brain material. The fields due to the handset, monopole, HFK wire and head, neck and torso are found with the finite-difference time-domain method. The fields in the head due to the handset alone are the reference case. When the handset and HFK are operated in free space the fields in the region where the head would be are found to be stronger than those of the handset alone. When the body is present, the fields near the surface of the head with the HFK depend strongly on the spacing of the HFK wire to the body. However, for the two cases examined, the field strength in the brain with the HFK wire is always smaller than the field strength of the handset alone.

How this classification was reachedexpand
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.
