Abstract:

The radiation characteristics of an axially oriented electric dipole in an isotropic plasma column are investigated. Surface waves are found to be excited for frequencies less than 1 square root of 2 times the plasma frequency. The dependence of the power carried by the surface as well as the space wave, on the frequency and the radius of the plasma column are examined. The surface waves are found to be excited with maximum efficiency in the neighborhood of 12 times the plasma frequency. The radiation pattern in the far-zone is evaluated and found to have, in general, a maximum in the broadside and a null in the end-fire directions. The normalized radiation resistance is found to vary as the square of the frequency for small column dimensions and for high frequencies. Author
