ABSTRACT
Before applying the theory of excitation and propagation of electromagnetic waves in density ducts, it is necessary to consider some properties of radiation from given sources immersed in a uniform unbounded magnetoplasma. This is important for two reasons: familiarity with this topic will facilitate understanding the problem of radiation from given sources in the presence of a duct; the radiation characteristics obtained for the uniform magnetoplasma will be utilized for comparison with those in the case of a plasma containing density ducts. The expressions for electric and magnetic fields excited by given sources will now be deduced. This chapter uses the Maxwell equations and notes that in all the field representations, the integration can easily be performed. It is necessary to determine the power that can be radiated from given sources into a homogeneous, cold magnetoplasma. This has an important bearing on future comparisons with radiation from the same sources in the presence of a density duct.
