Abstract

A numerical technique for gradient-type interface in the inverse scattering problems is presented in this paper. Such an interface is a point at which the velocity profile suffers a jump in first derivative. The time domain approach to scattering from gradient-type interface leads to an integro-differential equation. Using Legendre-Gauss-Lobatto nodes we construct the N^th polynomial interpolation to solve the integro-differential equation. An illustrative example is included to demonstrate the accuracy of the proposed method.
