Abstract
We present in this paper a comprehensive theory of antenna near fields in two parts, highlighting in particular the engineering perspective. Part I starts by providing a general conceptual framework for the more detailed spectral theory to be developed in Part II. This paper proceeds by proposing a general spatial description for the electromagnetic field in the antenna exterior region based on an asymptotic interpretation of the Wilcox expansion. This description is then extended by constructing the fields in the entire exterior domain by a direct computation starting from the far-field radiation pattern. This we achieve by deriving the Wilcox expansion from the multipole expansion, which allows us to analyze the energy exchange processes between various regions in the antenna surrounding domain, spelling out the effect and contribution of each mode in an analytical fashion. The results are used subsequently to evaluate the reactive energy of arbitrary antennas in a complete form written in terms of the TE and TM modes. Finally, the concept of reactive energy is reexamined in depth to illustrate the inherent ambiguity of the circuit total electric and magnetic reactive energies. We conclude that the traditional reactive field concept is inadequate to the characterization of the antenna near field in general.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
