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.
