Abstract
The propagation of whistler-mode waves at frequencies above one half the electron gyrofrequency has been investigated for a magnetospheric two-component plasma (cold and lower energy hot electrons) by use of the properties of refractive index surfaces. The presence of hot plasma is found to enhance the tendency towards field-aligned focusing of half-gyrofrequency whistler-mode propagation at large wave normal angles close to the oblique resonance angle of the whistler-mode propagation in the corresponding cold plasma.Keywords
