Abstract [en]

Dispersion properties of low-frequency (in comparison with the ion gyrofrequency) compressional electromagnetic waves in a nonuniform dusty magnetoplasma are presented. By using the plasma hydrodynamic equations together with the Faraday and Amp re laws, we derive a new dispersion relation. The latter is analyzed to show the relationship between various wave modes in dusty plasmas. The results should be useful in understanding the features of compressional electromagnetic waves in nonuniform astrophysical and laboratory dusty magnetoplasmas.
