Abstract : The report presents a Fortran IV WKB mode sum program developed for estimating round the world interference effects in the lower ELF band. The mode sum consists of the superposition of waves which travel over the long and short great circle paths to the observation point. WKB mode sum calculations are generated for the vertical electric field component, E(z), and the horizontal magnetic field component normal to the plane of propagation, H(y), excited by electric dipole sources of arbitrary elevation and orientation.
