The electromagnetic fields of a dipole in the presence of a thin plasma sheet

  • Published:
Applied Scientific Research, Section B

Summary

The problem of electric and magnetic dipoles located near a thin planar slab or sheet of ionized material is considered. A constant and uniform magnetic field is impressed on the slab. Under the assumption that the thickness of the slab is very small, expressions for the resultant fields are obtained. As a result of the anisotropy of the sheet it is indicated that the fields are elliptically polarized in general. On carrying out a saddle-point evaluation of the integrals in the formal solution it is shown that the far fields may be split into “radiation” and “surface wave” components. The dependence of the radiation pattern and the surface wave characteristics on electron density, collision frequency and the impressed magnetic field is illustrated.
