Conjugate gradient method applied to inverse scattering problem

- Haruyuki Harada, D. Wall, T. Takenaka, M. Tanaka
- Physics
- 1 August 1995

A new reconstruction algorithm for diffraction tomography is presented. The algorithm is based on the minimization of a functional which is defined as the norm of the discrepancy between the measured… Expand

Propagation of transient electromagnetic waves in time-varying media - Direct and inverse scattering problems

- I. Åberg, Gerhard Kristensson, D. Wall
- Mathematics
- 1 February 1995

Wave propagation of transient electromagnetic waves in time-varying media is considered. The medium, which is assumed to be inhomogeneous and dispersive, lacks invariance under time translations. The… Expand

ON INVERSE SOURCE PROBLEMS FOR THE ONE-WAY WAVE EQUATION

- D. Wall, J. Lundstedt
- Mathematics
- 1998

Abstract Inverse problems are considered for the linear one-way wave equation or transport equation. The equation is one-dimensional and nonstationary, that is, it has spatial and time-dependent wave… Expand

Transient waves in non-stationary media

- I. Åberg, Gerhard Kristensson, D. Wall
- Mathematics
- 1994

This paper treats propagation of transient waves in non-stationary media, which has many applications in e.g. electromagnetics and acoustics. The underlying hyperbolic equation is a general,… Expand
