Abstract
The pulsed electromagnetic radiation from a vertical
electric dipole above an atmospheric surface duct is
investigated theoretically. The duct model used is that of
Kahan and Eckart, consisting of a layer of relative permittivity
~2 overlying an infinitely conducing plane earth which is
confined by the plane z = 0 of a cartesian coordinate
system (x, y, z,). At height ”h”, the permittivity decreases
discontinuously to the value E 1 . The relative permeability y
is assumed to be constant throughout the half- space z > 0 .
The source of the electromagnetic field is assumed to be a
vertical electric dipole at a height ”d” (d > h) above the duct
with arbitrary time varying moment. The earth is assumed to
be an ideal conductor and planar.
