Dataset for "Stability and Characteristics of Lower-Hybrid Drift Waves: Dependence on Electron Beta and Cross-Field Relative Drift"

The dataset associated with this study consists of numerical solutions of
the local linear dispersion relation for lower-hybrid drift waves and
derived quasi-linear saturation estimates. It includes computed wave
frequencies, growth rates, propagation angles, and characteristic
wavenumbers over a two-dimensional parameter space spanned by electron
beta and normalized perpendicular electron drift velocity (normalized to
the ion sound speed). These data are used to generate five figures in the
manuscript: (1) benchmark comparisons between classical and
electromagnetic formulations of the dispersion relation, (2)
two-dimensional stability maps illustrating the transition from
electrostatic to electromagnetic regimes, (3) parameter scans identifying
the dominant control parameters for LHDW stability, (4) maps of the most
unstable mode properties as functions of electron beta and normalized
perpendicular electron drift velocity, and (5) quasi-linear estimates of
saturation properties, including normalized electric and magnetic energy
fractions, field amplitudes, and polarization ratios. All quantities are
derived from self-consistent linear solutions and post-processed using the
same reference plasma parameters described in the manuscript.
