Title: Reconstruction of generalized impedance functions for 3D acoustic scattering
Authors: Ivanyshyn Yaman, Olha
Keywords: Inverse problems
Boundary integral equations
Generalized impedance boundary condition
Helmholtz equation
Publisher: Academic Press Inc.
Abstract: We consider the inverse obstacle scattering problem of determining both of the surface impedance functions from far field measurements for a few incident plane waves at a fixed frequency. The reconstruction algorithm we propose is based on an iteratively regularized Newton-type method and nonlinear integral equations. The mathematical foundation of the method is presented and the feasibility is illustrated by numerical examples. (C) 2019 Elsevier Inc. All rights reserved.
