Short summary
This study explores the influence of temperature anisotropy and kappa-distributed suprathermal particles on electromagnetic ion cyclotron (EMIC) wave propagation in a multi-ion magnetospheric plasma. Results show that higher anisotropy enhances wave growth, while an increasing kappa value suppresses it, leading to thermalization. These findings have key implications for radiation belt electron loss and space weather modeling. Future work should incorporate nonlinear effects and observational validation.
