Abstract:
The voltages induced in dipoles and loop antennas immersed in a magneto-active plasma are calculated using the Rayleigh-Carson theorem for magneto-active media as derived in NRL Report AD-610 009. The voltage induced is given in terms of an effective length times the applied electric field, and in the present case the tensor dielectric character of the magneto-ionic medium complicates the effective length calculations. A first approximation for the effective length of a linear dipole in a magnetoactive plasma is derived which can be used if the antenna is short. Because loop antennas are also used in ionospheric propagation experiments, the ratio of the voltage induced in a small loop antenna to that induced in a dipole antenna is derived. Author
