Excitation of plasma resonance in a magnetoactive plasma by an external source. I. A source in a homogeneous plasma

The structure of the field of a distributed external source in a homogeneous magnetoactive plasma is found under the conditions of efficient excitation of plasma resonances by it with allowance for spatial dispersion and particle collisions. It is shown that at a distance from the source, the field loses the resonance character; parameters are found, the relation between which determines the degree of influence of electromagnetic, dispersional, and dissipative effects on the spatial evolution of the resonance structure
