A Current

The radiation field from a plasma-clad filament carrying a current I0 exp (−jkzz + jωt) is calculated. The plasma, which is finite in thickness, is magnetized in the direction parallel to the current filament. The field outside the plasma sheath is expressed by a combination of TE and TM modes, and in general the field is elliptically polarized. The conditions for circular and linear polarization in the far field are related to the thickness of the plasma sheath and the wave constants of the plasma.

Antenna Impedance

At high frequencies the time-averaged effect of the radiation field near an antenna is to add the term a2E2(r) to the Coulomb potential. Its inclusion in a self-consistent Poisson–Vlasov analysis shows that a high power antenna may acquire a strong positive floating potential.Electron, ion, and potential profiles are obtained from numerical calculations and the effect on antenna impedance is discussed. Time taken to acquire positive potentials is estimated.
