Radio Wave Propagation Revisited with Application to High-Latitude Ionospheric Scintillation
Bibliographic record
Abstract
The subject of radio-wave propagation in various media, including turbulent plasmas, has for more than a century preoccupied astronomers, space plasma physicists, scientists and engineers interested in the problem of wave scattering by turbulent media. We are particularly interested in the propagation of radio waves in the high-latitude ionosphere and the wave-scintillation signature as recorded by ground-based instruments. We first start by reviewing the universal problem of wave propagation in plasmas. We then identify the main approximations to be adopted to reduce the complex problem of wave propagation in a turbulent medium to a nonlinear wave equation. A new approach, based on analytical tools borrowed from quantum mechanics and statistical mechanics, is proposed to derive statistical properties of scintillation signals recorded by ground based instruments located in both the auroral and polar cap regions.

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.
