Abstract

The application of the stationary phase method is investigated for a dimensionless line integral encountered in wave propagation. Evaluation of the integral for a first‐order point of stationary phase may be expressed, characteristically, by the Fresnel‐Kirchhoff function or its derivative. A related function is found for the isolation factor required for finite limits of integration. Curves for evaluating this factor, K(u₂ u₁), are presented.
