Dipole admittance for magnetoplasma diagnostics

Abstract

A method is presented for calculating the admittance of a short thin dipole antenna in a cold collisional magnetoplasma. The theory is quasi-static, and the results are slightly more accurate than in previous analyses. Numerical calculations of admittance as a function of frequency are presented for several different orientations of the dipole with respect to the magnetic field. For any orientation the calculations show that the plasma frequency and the upper hybrid frequency can be readily identified.
