The electromagnetic nature oscillates through the interfaces with Plasma, impacting communication and control technologies, most notably in the domain of outer space. The refinement of prediction accuracy in space weather is my research goal in predicting electromagnetic wave attenuation in plasma media. The model incorporates parameters such as electron density, collision frequency, magnetic field strength, and wave frequency, thereby considering the real-time dynamics of plasma waves in the ionosphere and magnetosphere. Based on complex concepts of portions of Maxwell's equations and Fluid dynamics, this model calculates the signal attenuation at different levels of solar and geomagnetic activity. Simulation results indicate that during solar and geomagnetic storms, waves undergo significant attenuation due to diurnal and seasonal variations in plasma constituents. Overshadowed and validated by satellite-borne and ground-based observational data, the engineer-controlled model enhances estimations of communication blackouts and GPS signal misalignment surges resulting from irregularities in plasma fields. These outcomes further strengthen predictions of space weather threats, thereby improving efficiency and security in space communication and navigation systems.
