ELF and VLF radiation from the “polar electrojet antenna”

R. Graham Barr, P. Stubbe

Open publisher page 91 citations

Abstract

First, an approximate evaluation is made of the ELF/VLF dipole moment of the polar electrojet antenna established by ionospheric heating via the use of powerful HF waves amplitude modulated with frequencies in the ELF/VLF range. Then, the theory of reciprocity is used to determine the magnitude of the ELF/VLF waveguide excitation produced by such a dipole immersed in the ionosphere. Propagation under a series of ionospheres ranging from quiet auroral nightime to disturbed auroral daytime is considered.
