An elementary function that is closely related to the Sommerfeld flat-earth attenuation function is used to derive an alternative integral equation for propagation over irregular terrain. This choice of elementary function is shown to satisfy a scalar ‘parabolic’ wave equation. For the special case of a spherical earth, the integral equation yields more accurate results than previous general formulations; in addition, the integral equation is numerically feasible for both vertical and horizontal polarization.
