By adopting a 2D time-dependent wave code, we investigate how mode-converted waves at the Ion-Ion Hybrid (IIH) resonance and compressional waves propagate in 2D density structures with a wide range of field-aligned wavenumbers to background magnetic fields.The simulation results show that the mode-converted RED SUNSET PWD waves have continuous bands across the field line consistent with previous numerical studies.These waves also have harmonic structures in frequency domain and are localized in the field-aligned heavy ion density well.Our results thus emphasize the importance Lighting Accessories of a field-aligned heavy ion density structure for ultra-low frequency wave propagation, and suggest that IIH waves can be localized in different locations along the field line.
