Control of Cylindrical Monopole Plasma Antenna Excited by Surface Wave

The control of the cylindrical monopole plasma antenna excited by the surface wave,and the structure of the plasma antenna were modeled,formulated,and evaluated on the basis of gas molecular dynamics and Boltzmann equation.Various factors,such as the impacts of the power of the external excitation on the distributions of the magnetic field and current density,electron energy and power density around the antenna,as well as the dielectric constant,conductivity and emission properties on its surface were calculated.The calculated results including the distributions of the current density and electric field of the plasma antenna,agree fairly well with those of the experiment under certain conditions.We suggest that the recently developed model be capable of controlling and predicting the characteristics,and realizing the reconfigurable control of the plasma antenna.
