The classical and theoretical simulation for dominant radiated frequencies of plasma nanowire in presence of a long monopole antenna with long wavelength radiation

چکیده مقاله

A theoretical model based on the classical theory for the simulation of scattering phenomena of long wavelength electromagnetic waves from plasma nanowires is investigated. A line source as a monopole antenna radiator is considered, which radiates with frequency x in the vicinity of plasma nanowires parallel to the nanowire axis. A mathematical relation for resonance frequency is obtained. It is shown that in the resonance situation, plasma nanowires represent most of the response to the presence of electromagnetic waves. Mathematical computations are done for both the cold and warm approximations of plasma cases. The diagrams of the variation of resonance frequency versus the variation of temperature, geometrical dimension, and carrier density of plasma nanowires are presented. Also, a mathematical relation for subsidiary resonance frequency with considering two line sources with opposite charge is offered. The diagrams of subsidiary resonance frequency versus the variation of temperature, geometrical dimension, and carrier density of plasma nanowires are presented. It is shown that the presented model provides a color diagnostic system for the determination of size, the number, and distribution of nanowires immersed in a fluid based on their temperature and geometrical dimension.
