Parabolic Equation Starting Field For a Prolate Spheroid Source

Abstract

Parabolic equations are used to calculate the propagation of sound over distance. To use parabolic equations, one must be able to specify the starting field. At close ranges, the acoustic source should not be considered as a point source. The starting field is derived for the special case of a prolate spheroid source in an infinite uniform half-space.
