Source reconstruction from near field scan data of stripline structures

Inverse problems have always been a major subject in engineering science. There are still no standard solution algorithms working reliably without adding considerable amount of expert knowledge. This class of problems is often described by integral equations. These equations can be interpreted as a convolution of a source with the pulse response of a linear time invariant system. This suggests that it is possible to solve them in spectral domain. As reconstructing the sources of a near field scan data constitutes an inverse problem, the aim of this paper is to show an algorithm to determine an approximate solution. This involves the usage of the spatial Fourier transform and the corresponding impulse response functions in spectral domain.
