PlasmaWaves

Wave analysis for (space) plasmas, built in Julia.

Installation: at the Julia REPL, run using Pkg; Pkg.add("PlasmaWaves")

Documentation:

Features and Roadmap

• Wave polarization analysis with degree of polarization, wave normal angle, helicity, ellipticity, and planarity metrics
• Wave propagation analysis
  • SVD of the magnetic spectral matrix
  • Electromagnetic SVD
• Wave dispersion relation analysis

Quick start

using PlasmaWaves

# X is an N×3 array of field-aligned magnetic fluctuations
res = wavpol(X, fs = 128.0; nfft = 256)

res.degpol    # degree of polarization across time-frequency bins
res.waveangle # wave normal angle estimates

For SVD-derived planarity metrics, call wavpol_svd or twavpol_svd.

⚠️ Development Status: This package is in active development. While functional, the functionality is not fully tested (it has been cross-validated with a Python implementation in PySPEDAS) and the API may undergo changes in future releases. Please test thoroughly before using in scientific work.
