Short summary
Radiated electromagnetic fields from a PCB can be estimated when the source current distribution is known. From a measured near-field, the PCB source current can be found. Solving the given inverse problem with a system of linear equations and complex near-field data it can be very sensitive to noise. Regularization methods and an adjusted preconditioning can increase the accuracy. In this publication, an improved radiation model creation approach based on complex near-field data is presented.
