Abstract This article introduces a numerical technique for solving the inverse problem in dispersive scattering theory. The inverse problem is first formulated as a relationship between the impulse response R and the susceptibility kernel G. Using the Legendre‐Gauss‐Lobatto nodes we construct the Nth polynomial interpolation to approximate the solution of G for a given R. This method is efficient and yields very accurate results. Illustrative examples are included to demonstrate the accuracy of the proposed method. © 1995 John Wiley & Sons, Inc.
