Electrostatic dust-cyclotron waves in plasmas with opposite polarity grains

Electrostatic dust-cyclotron waves in plasmas with opposite polarity grains

The dispersion relation is derived for electrostatic dust-cyclotron (EDC) waves in a collisional plasma with dust grains having both positive and negative charges. The critical electric fields for excitation of two EDC modes in such a plasma are numerically calculated for a laboratory-type plasma.
