Abstract :
By use of the currents on the infinite cylinder excited by a radial dipole, approximate expressions for the two components of the far-zone electric field of a radial electric dipole near a perfectly conducting finite cylinder are derived. The validity of the approximation depends on the conditions, 
and 
, i.e., the cylinder must be long compared to a wavelength. The expressions are initially in integral form but it is shown that they may be evaluated approximately over most of the range of 
by use of the saddle point method. The theoretical results are compared to experimental results for a particular cylinder.
