A theoretical study of electromagnetic wave propagation in a spin-polarized quantum dusty magneto plasma using a modified quantum hydrodynamic model treating spin-up and spin-down electrons as distinct species. The formulation incorporates Fermi pressure, Bohm potential, magnetization currents, and dust-charging effects. The resulting dispersion relations for longitudinal, circularly polarized, ordinary, and extraordinary modes show that spin polarization produces noticeable low-frequency modifications, including an 20% increase in dispersion for the RCP and ordinary modes and 12% upward shifts in cutoff and resonance frequencies. At high frequencies, all modes tend to their classical limits. The results highlight the combined roles of spin asymmetry and dust charging in shaping wave dynamics in dense, strongly magnetized quantum plasmas relevant to white dwarfs, neutron stars, and high-field laboratory environments.
