LF, VLF, ELF PROPAGATION STUDIES. AUDIO AND SUB-AUDIO FREQUENCY EM WAVES PROPAGATED FROM SPHERICAL PLASMA SOURCES EXCITED BY ACOUSTIC PERTURBATIONS.
Abstract
An oscillating ionized plasma of finite size can be shown theoretically to be a new type of transmitter of EMwaves. Acoustic waves traveling through the plasma are postulated as a source of excitation of the EM-waves propagated from the plasma. The antenna pattern of the spherical plasma source of EM-waves energized by such acoustic waves can be quantitatively described. (Author)
