ELECTRIC DIPOLE RADIATION IN ISOTROPIC AND UNIAXIAL PLASMAS.

An investigation is described of radiation from an electric point dipole situated in a cold, collisionless, homogeneous, electronic plasma medium. Two limiting cases of a gyroelectric medium are studied. The magnetostatic biasing field is first taken to be equal to zero, making the medium isotropic, and then it is taken to be infinite, causing a uniaxial anisotropy. The retarded electromagnetic fields and the instantaneous and averaged values of irreversibly radiated power are calculated. In each medium, the partial differential equations resulting from the two-sided Laplace transformation of Maxwells equations with an oscillating electric dipole source and the constitutive equations derived from the appropriate form of the Lorentz force equation are solved.
