Radiation from a horizontal ring of radial electric dipoles, the strength of which varies as exp (jn?), is calculated for an unbounded medium by the saddle-point method of approximation. The cylindrical components of the radiated fields due to ring sources composed of radial, angular and vertical electric or magnetic dipoles, the amplitude of which varies as cos n? (or sin n?), are presented in a...
This note discusses the behaviour of separation Constants (which are also called transverse wave numbers) for electro magnetic-wave propagation in an anisotropic homogeneous cold plasma of arbitrary cross-section which is perpendicular to the direction of propagation (say z direction). Appropriate regions for which these constants are defined have been indicated in terms of inequalities among the...
