Wave packets of lateral waves due to a vertical monopole: Experiment and theory


  • M. F. Brown


A wave packet or pulse comprised of a distribution of single-frequency lateral waves due to a vertical monopole is analyzed. The Fresnel-integral terms in the Fourier transform of a general formula for E2z(ρ, z, ω), the vertical electric-field component in air, are represented using confluent hypergeometric functions. A wave packet of lateral waves is calculated for a pulsed short bare monopole at the boundary between a pair of Earth's material regions and compared with experimental measurements.
