Analysis of pre-processing techniques when using validation methods in computational electromagnetic simulations

In computational electromagnetic simulations, most validation methods have been developed to quantify the similarity of two datasets, making them an objective tool for test engineers to discuss data on a similar basis. However, these methods do not always agree with the expert´s opinion. The main problem when a validation method is used, is not taking into account the `pre-processing´ required by the expert to analyse a particular characteristic in the comparison. In this study, two different pre-processing techniques are used to show the influence they have on the results of the validation methods in relation to the opinion of the expert.
