A Convolution Integral with Highly Oscillatory Integrand - An Application to Pulse Rate Shark Repellants

摘要

An integral that arose when field strengths in seawater were calculated as part of an investigation into pulse rate shark barriers, is not amenable to numerical evaluation due to the strong oscillatory behaviour of the integrand. It is transformed by contour integration into the sum of an analytic expression and another integral that can be evaluated numerically.
