The characteristics of the virtual cathode and its potential profile in the presence of negatively charged dust particles have been reported by Rathod et al. They have studied the role of charged dust particles in the formation of virtual cathode near the emitting surface. Two conditions of the dust charge number, Z d = 1 and Z d = 1,000 are used to study the role of dust density ( n d ) for the formation of virtual cathode. This work is original and will be more interesting in case of using the correct model equations and realistic dusty plasma conditions.
